Goldfish Success
What it takes to keep goldfish healthy long-term

by Robert (Bob) Fenner

Re: catfish emergency   3/7/14
Greetings WetWebMedia crew,
I noticed some sort of insect larvae (looked like a small dragon fly larvae)
<Unlikely to be a dragonfly larva. But Anchor Worms are a possibility in pond fish, though extremely rare in aquaria.>
attached to the wound of my Pangasius. I tried to syphon the insect but it escaped. I don't think this is a normal parasite but in my fish's weakened state may be more vulnerable to attack.
<Indeed. But fungus and even strips of decaying tissue can be mistaken for parasites.>
The other possibility is that the insect could be beneficial, feeding on dead tissue. This is a large fish(24") and  has been recovering from a Columnaris infection(I've corresponded a few times in the last week or two in regard to the Columnaris infection).
My other problem is he is still not feeding. I've only tried floating and sinking pellets.
<Will when healthy. If unhealthy, won't want to eat, and trying to force it will mostly make things worse.>
I do have on hand a wide assortment of livebearers of all sizes, cichlid fry, red wigglers (composting worms) and  Neocaridina shrimp. I normally don't live feed any of my fish but under these circumstances I'm thinking of using these guys. I could also purchase brine shrimp. This fish is not skinny and has been living in a 2000gal outdoor pond with ample insect life (blood worms etc) and plant life,
<Ah, the plot thinnens. Do look up Anchor Worms.>
but hasn't fed in a month, to my knowledge.
<In a pond will likely have access to a variety of additional foods including insects, algae and decaying plant matter. Unlikely to starve.>
(this fish was given to me 30 days ago and broke out in Columnaris infection 24hrs  after arrival and hasn't fed since introduction). Any suggestions?
<See above.>
He  has been healing nicely in a 300gal hospital tank as side from that.
The fish seems active and the white tissue surrounding head and tip of caudal fin have disappeared. Although there are patches of red remaining,.
I've noticed if I shine a flash light he shys away, I'm hoping his vision is in intact. I've been doing 50% water changes every other day and he seems to really respond to that.
<When fish perk up after water changes, it's a good sign environmental stress/stresses are to be blame.>
Do you think I should be worried? Thanks for all the great information,
Brandon
<Hope this helps, Neale.>
Re: catfish emergency   3/7/14

Thanks for the response Neale. Although the insect larvae was definitely not an anchor worm. I'll try to capture and photograph. Thanks, Brandon
<Real good. Now aware of any insects that latch onto fish as parasites, though some will of course eat (very small) fish as prey, e.g., Dragonfly larvae. There are some crustaceans and leeches though that may parasitise fish, of which Anchor Worms and Fish "Lice" (Argulus spp., for example) are the most common. Cheers, Neale.>

Anchor worm? Recurring fin rot? Please help diagnose..   9/22/13
You folks helped me tremendously a few months back with my angelfish. I'm hoping you can assist me again. I have a 55 gallon tank with 5 adolescent angelfish, 4 blue rams, 2 Denison barbs and a Bala shark.
<This last will get very large.
.. might prove to be trouble for the other fishes; with its nervous, "jumpy" behavior>
All of them together are about 17 inches of fish. They don't seem over-crowded yet, but if you tell me that's my issue, I will fix the situation.
<Will be an issue w/ the Bala in time>
 I am trying to let them pair, and then rehoming them. I recently had to treat for Camallanus worms with Levamisole. These worms didn't show up until 2 months after the fish was added, and I have added no new fish, plants, etc since. The Levamisole seems to have worked, but I will still administer the second dose next week. My biggest problem now is a blue ram with a red thing sticking out near his anal fin.
<I see this>

 It is bigger than the Camallanus worms, and there is only 1 It looks like a piece of red toothpick stuck in his side normally. However, when he gets angry, or during feeding time, it appears more like the "thing" comes out of him, then loops back up in him. It comes out if his side, not the anus.
He is very aggressive at meal time also. I have (in a QT tank) tried Metronidazole, Praziquantel, CopperSafe, Methylene blue, salt baths/dips, Nitrofurazadone, and he was in the main tank for the Levamisole treatment.
<None of these will treat for Anchorworm>
I have not seen anything like this on any other fish, and I can't diagnose.
I've researched and looked at so many pictures and descriptions, my brain is scrambled. I keep thinking it's an anchor worm, but no new ones have appeared, and it doesn't fork at the end.
<May in time or not. Still could be Lernaea... I'd catch this fish now, hold gently but firmly, and pull this out carefully with a tweezers>
It looks like "color", until he swims away from you, and the anal fin moves, but the "thing" doesn't. I would be so grateful for your opinion on what this could be. I'm going to ask a few other questions, because I wonder if all my problems aren't related. Two of the angelfish keep getting pinholes in their dorsal fins, and the dorsal looks raggedy.
<... this could be "nothing" disease wise. Would NOT treat for>
They also have missing scales, or little indents in their sides, that I thought were the result of pecking, but I never see pecking, and now I wonder if it's not bacterial!
<More likely the Bala Minnow Shark or medicine exposure; can't see much in your images here>
 I've attached a picture of my black angel, who looked like he scraped a piece off his side near his dorsal fin. It looked like mowed grass. It looked that way on both sides. These things keep happening. The indents and patches go away on their own, but it keeps happening. My parameters are good, but I try water changes anyways. Then, I treat with KanaPlex.
<A poor idea to keep pouring in such>
The fins get better, but it keeps coming back. Another odd symptom is that ALL the fish seem to tap their bellies with their ventral fins, as if trying to get something off. I've even seen a ram rub his belly in the gravel (not during breeding). I'm sorry for throwing so much information at you, but no one seems to have any idea why I keep having problems. I medicate (except for the Levamisole) in a QT tank. I only use medication when I fear the fish is dying. I try everything else first. The blue ram is a part of a pair that has laid eggs twice. I'm really hoping to diagnose and treat him. I would also like to keep the angelfish healthy, as they seem to be starting to swim in "twos", so any suggestions on their care is appreciated. I do weekly water changes with prime. My tank cycled 3 months ago. Readings- ammonia, nitrites: 0. Nitrates: never over 20. Ph: 7.2. GH: 7-8, KH: 5-6. I use 2 filters, a Purigen, sponges, and a nitra-zorb. No carbon. I mix 1/4 tap with 3/4 RO water. I was wondering if this might be making the ph shift, causing the fish to stress, and causing my problems.
<Not likely; no>
I test replacement water for kH, gH, ph and temperature. But, I don't add buffers or other chemicals. Does RO water need trace elements replaced and/or something added to keep ph stable?
<Not if made up some other way; in this case mostly by the 1/4 tap>
 Or is the tap water enough of a buffer?
<According to your test results, yes>
One last question: can a fish KEEP getting the same illnesses, or do they build immunities?
<Some acquired immunity for some infectious, parasitic diseases has been demonstrated/observed in many fishes>
 I feed them blood worms
<Stop! Do search the net re these Chironomid sewer worm larvae. I would NOT use them, or restrict their use>
or brine shrimp soaked in vita-chem in the morning, and omega flakes at night (all eaten in 3 minutes). Any help is greatly appreciated, as I'm really hoping to breed these fish.
Thank you,
Kelly
<Thank you for sharing. Bob Fenner>

Anchor worms - Help!!     8/18/13
Hi WWM,
<Kristen>
I made a foolish mistake and added 3 juvenile Boesemanni Rainbows to my established 60 gallon tank (populated by 3 silver dollars, 2 pictus cats, and 2 adult Boesemanni). I bought them from the same reputable seller where I'd bought their tank mates between 5 and 3 yrs. ago. No, I didn't QT them.
No obvious signs of infection were present & I took a gamble. Kicking myself now!! My water quality is always good (I make sure that the nitrates are below 25 ppm & do twice monthly water changes). I am by no means the most expert fish keeper, but I am not a newbie & have been maintaining 4 healthy tanks over the past 12 years.
<Happens>
To cut to the chase, these new Rainbows were infected with anchor worm (I actually removed some w/tweezers & salt & confirmed their identity) which I have never seen in an aquarium.
<These two are seasonal infestations... from pond-raised fishes>
Some of my pond Koi had this a couple of years back - I treated w/Anchors Away & they pulled through just fine. They are large fish, though. These small Rainbows were not so lucky, as they had multiple worms coming out of their gills and near their eyes, that showed up within a week of purchase.
I've ordered Hikari CyroPro & it's on it's way, but unfortunately, those poor fish all succumbed.
<Ahh!>
I am REALLY worried now because my Silver Dollars started displaying what I thought could have been the beginnings of Ich, only on their fins, and I was going to treat for it (already raised temp. to 86) but now it looks to be turning into these same worms!!
<Actually crustaceans>
Is that possible, so quickly?
<May be>
 Would it only be showing up on the fins?
<Not usually, no>
I think I've seen nearly every other kind of FW fish disease, and this doesn't look like any of them. I do not have a pic because the lesions are still pretty small & the fish won't sit still.
My main question is: do I treat immediately for anchor worm, or should I be more concerned about the possibility of Ich & treat for that first?
<Not Ich... and/or the elevated temp. will take care of. I would treat for Lernaea>
I really DON'T think it's Ich now. Maybe I was just seeing the lesions where the tiny copepod larval stage was attaching itself?
<Again; possibly>
I feel inclined to treat for the anchor worms right away...
<Yes; I would>
Thank you in advance for your help!!
Kristen
<I take it you've read the bit we have on these pests/parasites on WWM.
Steady on, Bob Fenner> 
Re: Anchor worms - Help!!      8/19/13

Bob,
<Kristen>
Thank you so much for your input! You've reassured me that I'm on the right track. I'll keep my fingers crossed and hope that all goes well.
Best,
Kristen
<Please do send along notes re your further experiences, observations.
BobF> 

Re: Anchor worms - Help!!     8/20/13
Hello, Bob-
<Kristen>
Thank you for your continued assistance! I actually would like to have your take on the current state of the fish, if you have time.
<Sure>
I finally received the CyroPro,
<Hikari product; cyromazine (N-cyclopropyl-1,3,5-triazine-2, 4,6-triamine).

No reviews on Amazon.com...>
 did the requisite 90% water change, and now, four hours later, the Silver Dollars' fins look like this (see attached). It happened very quickly. The Pictus look fine.
<Burn baby burn>
These aren't the best pictures - sorry! There are dried water droplets on the glass, casting shadows, so that's what accounts for the dark spots. The fins are not ragged, just looked a bit cloudy prior to the dosing (no more Ich-looking lesions), but they started to display this within an hour or so of dosing. Very strange! I hope that the medication is just taking effect, and may have simply irritated the growing parasitic crustaceans.
<Maybe... I do see what appears to be an adult Lernaeid on the anal fin of one of the dollars. Have cropped two of your pix and tried to enhance (posted on WWM)>
I did pull a smallish worm off of my largest Rainbow, near the eye. It came off very easily, a couple of hours after dosing w/the CyroPro. I've read that it works by interfering with the growth of exoskeletons. Anyway, I just hope that I'm doing the right thing to help my fish!
<Yes; this is what I'd do as well>
Thanks for your input!
Kristen
<Thank you for your ongoing sharing. Bob Fenner>

Re: Anchor worms - Help!!      8/21/13
Hi Bob,
<Kris>
Yes, I did pull a worm off of an SD today.
<Ahh>
I sure hope the CyroPro is working! I don't know how effective it is against fully mature Lernaea.
<Not nearly as much as young, intermediates>

 I can now see one protruding from the inside of a Rainbow's mouth. I think this is a strange and particularly aggressive form, which, at least in the Rainbows, seems to specifically target their eyes, gills, and mouth areas.
<Yeeowch!>
It's a 3 week long course of treatment, so I'll just keep hoping for the best. Thank you again for your help! If anything significant happens, I will send an update.
Best,
Kristen
<Thank you, BobF>

Red Devil with sore/parasites <Lernaea?> 12/31/12
Dear Crew/Neale/Anybody,
<This is Rick, but I'm leaving this note in the inbox so Neale can take a crack at it also..>
Where do I start.....
First off.....I am a advanced fish aquarist, I know my stuff so I will get right to it so to speak. Please bear with me I am not a good letter writer.
<No problem>
I have a Red Devil ( Midas)  he lives alone in a 110 fish tank, age  almost 2.  He has been thriving and doing beautifully for at least a year.......all of a sudden Bubba develops a sore about the size of a dime, it  happened within a matter of two days!!!!!!!!!!   When I first spotted  it I about dropped over, in hindsight I should have recognized his behavior was  off, he wasn't greeting me or eating as robustly, I mean he literally jumps out  of the tank for his pellets.   Attaching you tubes so you can see the  sore when it first was spotted.  It was horrible, I knew I had to get him  on something quickly, I started him on Furan 2.  After two days the sore  came to a head and I got my fish out of the water and I lanced it.......pus came  out and I swabbed it with A&D.  I put him back into the tank with furan  2 for two more days and it started to mend nicely......so I put him back into  the 110, I just use salt and Melafix and thought I was on my way to healing, I don't like to medicate fish, I don't even use carbon in my filters!
<sometimes necessary.>
Yesterday I did a large water change and his sore was ok, today I looked at my fish and I am besides myself........inside the sore two worm like things are  hanging out and one is actually coming out of his gill at the bottom, it's  red/blackish, I am going to attach a video of that when I finish typing this to  you.  
<I did not see the parasites in the videos.>
Evidently the Melafix isn't working, so I don't know what to  do!!!!!!!!!   Should I get him back on Furan 2, or Parasite  Guard?   I have both in the house.  Do I pull those wormlike  things out with tweezers?  I am besides myself here not knowing what to do  now........He was doing beautifully, the sore was mending, how could things pop  out of the affected area over night?  
<Hard to predict when you don't know the root cause in the first place. The MelaFix might be helping the sore itself but worthless against parasites.
Take a look at this page:
http://www.wetwebmedia.com/fwsubwebindex/anchorwrmfaqs.htm and see if the parasites you  observed match Anchorworms. It's a place to start, anyway.>
My water params are fine, I am a breeder of cichlids, I raised Discus so I know water changes trust me. 
<Trusting, but for the reference of people with a similar problem who check this forum five years from now, the parameters are useful.>
This fish gets water changes weekly at 60% 
and always has since a baby.   Please get back to me email wise so I  don't get lost in the shuffle.   I need help asap, I can't sit and do  nothing here, this fish is my child fcs.
<Start with the Anchorworm FAQs I linked. It has a photo at the top of the page.>
I appreciate any help or advise, Neale you helped me long ago, I hope you or anybody can come thru for me now.   I am attaching three video's so  you can see my dilemma.  BTW, My fish has never eaten a feeder fish in his life, I know they are worthless. 
<I'd say feeders are risky rather than worthless. Depends on a lot of things, but I digress.>
First Video of the sore  ~~~~~~>   _http://youtu.be/06TisLU6ILs_ 
(http://youtu.be/06TisLU6ILs)
Another vid of the sore ~~~~~>      _http://youtu.be/JO-jARSQBf0_
(http://youtu.be/JO-jARSQBf0)
it started to mend very nicely after I lanced it, something has happened literally overnight with these things protruding out from that affected area.   Plz Somebody Help Me!
<Surely the parasites were there when you lanced, only out of sight.>
Can you please email me back so I don't lose my correspondence in the muck of things.  Thanks very much, sigh, I am besides myself.
This is what is happening now ~~~>   _http://youtu.be/dOd5jmjETyo_
 (http://youtu.be/dOd5jmjETyo)
<Let's start with comparing to Anchorworms and also see what Neale or Bob can contribute.
- Rick>
Re Red Devil with sore/parasites 12/31/12
Rick,
<Julia>
Thanks for getting back to me so quickly, especially on a night when we all should be out having a good time sigh.  Just having somebody know my  problem has made this a lot easier on me.
<Sharing the load often helps.>
I did read about the anchor worm, and I think you hit the nail on the  head!!!!!!! 
<Ah, good!>
When that sore first started, it was the worm/parasite working  it's way out, when I lanced that area, you were right again, it didn't show
itself yet and that is why I didn't see it at all.  I do believe the  Furan 2 and the Melafix helped him survive that outbreak but now the worms are  showing their ugly heads, they are to small for me to grab, and like the article said when the fish comes out of the water they suck back inside......how on  earth am I ever going to be able to grab it.....I feel I need to wait until the  worm/worms are hanging out more before I even attempt to do anything at  all. 
I did get Parasite Guard into his tank, I knew it was a parasite of some  kind today when they came out and showed their ugly heads, I know I am going to  have to do a surgical removal on them, I have no problem saving the life of my  fish, I have to do this for him but I feel I can't grab it now it's to  small......what a horrible situation I am in here.  My sister will have to  assist me yet again while I do this.
<I had similar trouble with a nematode outbreak a few years ago. Frustrating.>
I am going to wait two days to see if they come out more, I have salt in  the tank along with the parasite guard, 1 tablespoon per ten gallons of  water.   I don't have the heart to put him back into a 50 gallon tank  at this point, he's just to big now, so I have to keep him in his own 110.
<Well, it may be wise to move him anyway. Much easier to treat in a smaller volume of water. If the eggs have hatched, there will be free-living juveniles in the water that can remain alive without a host at least five days.  According to my favorite book (Manual of Fish Health by Andrews, Exell and Carrington, best work for a reasonable price) the tanks should be treated with an organophosphorous  insecticide such as metriphonite, but there may be better proprietary options out there. (Neale/Bob??)  Says to allow active ingredients to dissipate over ten days at summer temperatures, so probably longer this time of year.
Also, for the adults, swift removal with a fine forceps, which might need repeating after two weeks or so if others emerge. Dab area with a topical antiseptic. Book recommends mercurochrome. Minimize time out of water.  I'm not sure how available these kinds of meds are to regular people (as opposed to veterinarians).
Is there anything else I should be doing while waiting on the worms to show? 
<I'd still move to the smaller tank and perhaps feed an antibiotic food as part of the diet. Infection is a concern here.>
I will also state that my fish is oblivious to being ill, he's  eating as always and is demanding as ever,  it breaks my heart to see these things
hanging out of that sore though, I swear this hobby is going to do me in if  I lose him.  
<That he is still strong is a positive, for sure.>
Also I wonder what brought this on?  I have sand as  my substrate and I am always careful to stir it on water changes because of  anaerobic gases etc, I wonder if I laxed in some way perhaps wiping down the  sides of the tank, I have NO idea what brought this on.  Old food  maybe?  I don't give night crawlers to him either.   His diet is  varied in all ways but his main staple is Hikari Gold Pellets.
<Hard to say. I don't see any obvious vector unless maybe you added new plants or inverts recently.>
Oh a question.....should I bump up his heat or keep it at 78-80?  What would help the most?
<I honestly don't know as my book says nothing on this topic. Lacking any other information, i would keep the tank at the optimum temperature for the fish.>
I will wait on hearing from Neale or Bob Fenner ( I hope he is kind  ;-) )
<Oh, Bob is a sweetheart.><<Oh, I wouldn't go this far. B>>
and see what they have to say back to me.  This fish has stolen  my heart.....I have a female RD and I love the species.  This is my third  RD, but Bubba is more Midas and is a beauty and very girthy and much wider than  a regular RD.   I am rambling now, so I will close and wait to hear  back from the others.   Have a safe and sound New Years Eve tonight,  my best to you all at WWM.         
<Good luck>
 Sincerely, Julia

Anchorworm issue    12/31/12

Bob/Neale
Just FYI, there are two emails in the freshwater area from somebody fighting Anchorworms. I answered the queries, but left them in the freshwater area in case you want to comment or add something to what I told this person. I've not dealt with Anchorworms before so everything I said is right out of my books.
Rick
<Will take a look. Thank you Rick. B>
Neale or anybody please help me......plz plz help me.    12/31/12

Dear Crew/Neale/Anybody,
<Bob Fenner here, WWM's common progenitor. Rick asked myself (and Neale) to look over your messages, his responses. I do concur w/ his statements and encourage you to read the prescribed link on Anchorworms. These crustaceans can be eliminated w/ the instructions detailed there>
Re: Neale or anybody please help me......plz plz help me. (Maybe not Lernaea)   1/1/13

It isn't obvious to me what's the deal here, but my guess is some sort of ulcer. Whether there is also a parasitic infection of the skin as well is hard to say. In any event, I'd medicate the tank with both Metronidazole and Nitrofurazone, and I'd also use seawater dips (aquarium or marine salt, 35 gram/litre).
Such dips are very good for cleaning external infections and preventing further decay of the skin. Amphilophus spp. have a high tolerance for salt, so anything up to 20 minutes will be suitable -- remove the cichlid before that time if it shows signs of severe distress, such as rolling over. Do make sure the seawater dip is the same temperature and approximately the same pH as the display tank.
You could also add salt to the display tank at 3-5 gram/litre. Won't do any harm and may do some good.
The aquarium does look rather small for this fish.
Cheers, Neale
Re: Neale or anybody please help me......plz plz help me  1/1/13
> Ok I am still at a stuck point.  Parasite Clear has the metro it in.  Furan 2 has the Nitro in it....Two products I have and are using but not at the same time.  I am going to finish up the rounds with Parasite Clear, in two days I am going to see if I can tweeze out whatever is in that sore.  I will finish up the recommended amount.  Then I will move him over to Furan 2, continue the salt.  Is my fish going to be able to withstand all this medication?  I am going to go to Wikipedia now. 
<Should be fine but do 25-50% water changes between finishing one set of medications and starting another. Keep water chemistry, temperature the same. Cheers, Neale.>
Re: Neale or anybody please help me......plz plz help me  1/1/13
> Neale thanks again for all info.   I am going to tackle this, I must do this for my fish.  I only wish I knew how he got this Neale, it scares me not knowing for sure.    I will let you know what happens after all the meds have been giving and what I get when I tweeze out what is hanging.  I am scared to do this but I have to.  Julia
<Good luck. Next time, do please try and write via WWM rather than our personal e-mails; that way, other crew members can chip in, and hopefully, WWM readers can benefit from your experiences. Cheers, Neale.>
<<Ah, t'was I forwarding the query to you Neale... to speed a response along. B>>

parasites in fish and humans... Lernaeid confusion      7/26/12
I had an anchor worm problem this year with some of my  1-2" goldfish that I had in a brand new 600 gal pond that  I dug up this spring. I only had about 10 small goldfish in the pond, but the  pond was drying up fast from the lack of rain this year 2012, so I moved the  fish back into there 25 gal tank inside the house.
After about a month fish started to die, I had no idea  what the problem was till there was only 3 fish left, then I started to look  real close and that’s when I noticed the anchor worms, new to this problem I  treated the tank with PraziPro,
<... Anchorworm is not a worm, but a crustacean parasite... Prazi won't cure it. Read here: http://www.wetwebmedia.com/FWSubWebIndex/anchorwrmfaqs.htm
and took out the carbon out of the filter, but  it was to <too>
late for the fish. 4 days later after I treated the tank I took the  dead fish out and looked at the worms with a loop and I can see that some were  still alive. My question is how long  does it take for this product to kill the worm?
<... it won't. Read... >
Also how does  this parasite effect frogs and tadpoles in a pond? 
<Won't hopefully... unless worms present dying cause issues>
And the most important question I have is If children  or adults are playing in a small pond like mine catching frogs and tadpoles that  is infested with parasites/anchor worms and eggs and someone gets these  parasites or parasite eggs in an open wound/mouth/eyes will they become a  problem and how will it effect the human body?. Thanks  Frank
<Won't affect humans either... but, cheap/comet goldfish in America invariably have several infectious and parasitic issues...
I'd keep them out of the pond. Bob Fenner>

Goldfish blood spots 10/29/11
<Hello Hope>Are u able to tell me what to do about blood spots on some of my goldfish? <Likely to do with water condition, tank size> What can I do about them and why do they have them. <As above> I feed them frozen food and flakes. I change them a thirty gallon tank. <Assume you mean you have
them in a 30 gallon tank. How many? Goldfish are messy and in this size more than a couple of fish will likely make water conditions poor> One time per month. <Needs to be more often. Small water changes around 15% weekly> And add something to the water as per the dosage suggestion on the bottle. <What? Assume this is some kind of conditioner to remove chlorine and other toxic elements in tap water?> It is something for their bodies and the water. <Again, you really need to get with the basics and figure out what you are adding to the water. Aquasafe is a brand that works well for what I have mentioned above> I forget the name off hand. I do about half the tank change.<As above, smaller changes, more regular> And add water. Just a little during the month when the water evaporates. Thanks
for your help. <From the above description it does sound like you have an issue with water chemistry that is likely resulting in poor fish health. Please test you water for ammonia, nitrites etc. You also want to look at the number of goldfish you have in this space. You can read more about caring for your fish here -
http://www.wetwebmedia.com/fwsubwebindex/goldfish.htm
Good luck! Sugam>
Re: Goldfish blood spots 10/29/11

Hi and thank you. <Hi Hope, sorry to hear about the loss> I took a water sample to the fish "whisperer" <Hehe!> this a.m. He tested for everything. Including ph, nitrates nitrites. All well. <Good. That's one area ruled out.> One fish has already succumbed to it. Two had it. Now one. The others. No. He is stumped as well. He is a local but a very knowledgeable person. So I trust his judgment. I use Amquel when I
do the change one time per month. I would almost describe it now on one fish as a parasite. <Have you added fish or anything else lately? I would think linked to stress from crowding/conditions has made them vulnerable to secondary infections > Maybe I will send you a photo of the remaining fish to this email address. Via the iPad. He said give it 72 hours and then he would come by and take a look. I will however follow your advice and change the water more frequently and less taken out. <Good! These helps keep the water conditions stable and good. About 15-20% weekly> Maybe.
It's too much to take out so much. <More of an issue of changing it less frequently than needed> Less is more. I appreciate that you answered the question(s). It almost seems like it is easier to keep guppies!!!!! <Yes. Goldfish, despite the way they are advertised, are not the easiest to keep and as I mentioned before, require lots of room.> I have four good sized goldfish in a thirty gallon tank... <Did you read the link I sent? That's not enough room for them.> Again. Maybe less is more!!!!????? <Indeed>

Hi and thank you. I believe that those blood spots are in fact anchor worms!!!!! <Yikes! I have experience with these from a massive outbreak when I first set up my tank. Nasty creatures and difficult to get rid of them.> I went to the pet store and got a product called clout. <Not familiar with this product but do keep in mind that most of the medication that is specifically for anchor worm is highly toxic (for you and for other pets)> I have a thirty gallon tank. I placed. Three tablets in the tank as per the directions 2 days ago. Repeated the three tablets the next day and was told to do a small water change today by the "fish whisperer".
They are no better. All the fish have them now. They appear to be lesions with a bony appendage like sticking out of the lesion. <Take a look here. May help you make a firm identification -
http://www.wetwebmedia.com/fwsubwebindex/anchorwrmfaqs.htm
Actually. I bought a fish unknowingly a month or so ago. From the shop and saw a lesion and projectile on the fish after my purchase. I did not notice it in the store before my purchase..... Only when I got home and put it in the tank. It never seemed sick though! <Yes. Sounds about right. The way these critters operate makes the fish look mostly healthy in the early stages.> In fact I believed it was injured somehow on the way home.
<Unlikely if you see a wound with a small whitish tail hanging out of it.>
In a few days the lesion and bony protrusion disappeared. <Not entirely bony but it is a firm protrusion for sure.> I guess it was the worm falling off and the fish healing. <These critters attach to fish for nutrition and have a life-cycle of their own.> Now I guess the eggs have multiplied and are attaching themselves to all the fish. <Would seem to be the case.>
They seem very active however I realize the fish will succumb to the parasites unless I can rid of them. <Aha! yes> What do you suggest I do now knowing that I have administered clout for 2 days and have done a slight water change. I really appreciate any help you would be able to give me. You doing a great service for people. Thanks <Hope, the approach I am about to propose isn't conventional to say the least but I did find it effective with the infestation I had. If your fish are of a decent size, dip them for a very short while in salt water. This will weaken the anchor worm's grip and then you will be able to pull out the worm with tweezers (the fish in a net, not in the hand). Please be extremely careful when doing this! If you don't get all of the worm out, it will just regrow and if you pull too much, there is a chance of killing the fish. Please look at adding some kind of antiseptic post this treatment so your fish don't pick up secondary infections. Do keep in mind that this proposed approach may be too much some of the fish but will certainly help with most. Was shown this technique by my own "fish whisperer" and it proved effective in my case. I wish you luck! Sugam>

Re: Goldfish blood spots now identified as anchor worm 11/4/11

Hi. <Hello again Hope> They are definitely anchor worms. <Okay that's half the battle won. Now we know what to treat.> I will try to do what you suggested when I get up some nerve. <As I said, there is also medication specific to this issue but use with caution. It is highly toxic and by that I mean not just for the fish!> How do I make the salt solution <In a bucket. First add water, then sea salt (not table salt). About 100-120 grams per gallon should do the trick. Wait for the salt to mix in completely and the water to become clear. You will need to put a small powerhead in the bucket to help stir the solution. Dip for about a minute and keep a close eye on the fish. If the fish seems to be too stressed by the dip, remove immediately. The worm should come out easily immediately after the dip. I do realise that this procedure sounds quite rough and as I said before, it is definitely unconventional. Please do consider whether
you would like to pursue this route or whether you are more comfortable dosing a medication under the supervision of a vet. Either way, I would recommend treating the fish soon before the anchor worm weakens it to the point of no return. Do remember to add some kind of antiseptic (Melafix perhaps) post removal.>
How much salt. How much water. <As above> Thanks <Good luck! Sugam>
Re: Goldfish blood spots now identified as anchor worm 11/5/11

Hi. I just am not able to do this. <Hi Hope, as I said, the prescribed approach does sound harsh but really is the best way to go.> it is very sad to see these beautiful fish being infected by the parasite. <Indeed> Here is what I did. For 2 days I used the clout as prescribed. On the third day I removed a small amount of water and replaced it with new water I stopped the medication because I had already used it one more day than it said to use it. <I am not familiar with this medication but you can find but there are many brands of pesticides that will help treat the infection in the tank. Do follow the instructions exactly. Too much risk of toxicity here.> Yes. I realize that the medicine is very toxic. Basically I haven't come into contact with it. The fish are no better. Now all of the have the worms. They have spread and some have four or five on them.
One, the one that came in with the parasite and infected the others now has one on the edge of and a little inside his gill therefore I could not remove it. <Yikes! Please do remove the worms from the other fish as recommended and quarantine the one with the massive infestation if you haven't done so already.> When I saw that I gave up sorry to say. I am thinking that I should repeat the medicine. <Again, not familiar with the brand but from your description, does not look like it is working.> If so.
How much, for how many days and when should I begin again. If I loose <lose>the fish, and I hate to be pessimistic here what should I do to the tank to decontaminate it before placing other fish into it? <The pesticide based medications will decontaminate the tank.> How long would u say the eggs can live and under what conditions? Should I discard the gravel?
Rocks fake plants? Once again. <Once the treatment is done, please replace your carbon in the filter. Assume you have removed the carbon during the treatment?> Thank u
<Hope, I do believe the best approach is manual extraction. I am also putting your questions to the rest of the crew to see if there is any further they can offer or something I may have missed. Cheers, Sugam>

Re: Goldfish blood spots now identified as anchor worm 11/4/11 11/19/11

sort of at a standstill here no better no worse yesterday I took the plunge and removed five of them the worms that is it is a very very tricky maneuver because just for you and other people's information when you remove the fish from the water the worm which is translucent blends into the fish body and it's very difficult to see it even with a magnifying glass which I tried to use. Definitely they are anchor worms! Thanks for your recent help. <You are welcome. Really glad you tried the suggested approach! I agree on being quite tricky but really one of the only ways to go with anchor worms. I am sure you did this but ensure you get all of the worm. If it snaps, it will simply grow back. You should now see some gradual improvement in the fish. Do remember to treat with iodine or Melafix! Cheers - Sugam>

Unusual tag-like growth on black moor, Lernaea 6/21/11
Hello WWM crew,
One morning I woke up and noticed my black moor developed this flat white-grayish growth near its dorsal fin. It is difficult to describe as it's not quite a growth but more like a tag. Regardless it does stick out from the fish's body but there is no red sore near its base. The "growth" does seem to have a head of some sort that is slightly whiter in colour while the "body" seem more translucent.
At first I thought it was a parasite but after a few days of research online, I cannot seem to find a description that would match what my black moor has. It does not have a forked end like an anchor worm nor is it moving on its own. Although it looks string-like it isn't really. It's flat. As a precaution I isolated the black moor from the two other smaller goldfishes I have into a smaller tank. I added aquarium salt and a bit of Fungus Clear to the smaller tank and observed the black moor carefully. I also did daily water changes for three days and a change of carbon filter with the main tank as I noticed that the water is cloudy and has a smell to it. Perhaps it's not a coincidence but as soon as I removed the black moor from the main tank, the water quality improves.
A bit of history: the smaller goldfish developed a split in its dorsal fin and out of fear that it's fin rot, I treated the whole tank with Fungus Clear. It cured the fin rot but my black moor became lethargic. It would sit at the bottom of the tank. I placed the carbon filter back into the tank, did a 50%-60% water change, gave the black moor a salt dip, and everything seem to be fine. (In the past the black moor can be frequently observed doing some flashing but a quick salt dip usually lessens/eliminates it.) About two weeks later, the growth appeared.
The black moor still rubs its body against the bottom of the tank but other than that, it shows no other unusual symptoms. It eats and it's energetic.
(The fish moves so much that it took me a very long time to get a good photograph.) There are no open sores, no gasping that I am aware of, and no unusual spots. It had a small split in its dorsal fin a few days earlier but the following day the split mended itself. It has been three days since I've isolated the black moor and there seem to be no significant changes.
The tag could be growing longer but it could also be from staring at it for three days. I am at a complete loss as to what this is. I don't want to re-introduce the black moor back into the main tank for fear of it spreading whatever it has to the other fishes. The Fungus Clear didn't seem to have had any effect.
I've included some pictures and here's a video in case it helps:
http://imageshack.us/clip/my-videos/543/d1n.mp4/
Any insight into this would be very much appreciated. I am completely at a loss as to what to do!
Sincerely,
Jenny
<Hello Jenny. Does look like Anchor Worm or some close relative. Can be treated with Anchor Worm medications -- essentially insecticides -- ideally under veterinarian supervision because these are quite toxic (including to you and your other pets). Alternatively, if it's just the one fish, try dipping in seawater for 30-60 seconds (i.e., 35 grammes sea salt in one litre of aquarium water) to weaken the Anchor Worm, then cleanly remove with forceps. Try not to damage the fish by tearing; if the salty water has done its job, the worm will loosen up. If it isn't loose, dip again. Short dips in seawater won't harm large fish if you're careful and remove before it becomes obviously distressed, e.g., by rolling over. Dab the fish with iodine ointment to clean the wound, or alternatively, medicate the water with some sort of mild antiseptic, such as Melafix. Hope this helps, Neale.>

Re follow-on to answer on 6/19 - goldfish with small bump 6/22/11
Hi again,
<Salve!>
I just wanted to follow up on your reply (I've put it at the bottom of this, for your reference) over the weekend for me; I do appreciate Neale having put in the time to reply. I'd like to clarify, and make sure we're both talking about the same thing. Hagen has renamed/renumbered their filters somewhere in the last 5 years; the 110 is rated at 500 gallons per hour (it used to be called the 500), so I think that puts me safely over the 6 changes per hour that your FAQ talks about for my 75 gallon tank; would you still consider that to be a modest filter?
<It's fair to middling, about what you'd use for a community tank with tetras, barbs, etc. Whether it can handle the sheer volume of mess created by Goldfish is a whole other matter. If you have zero ammonia and zero nitrite, and your tank isn't murky, and the fish don't gasp at the surface for oxygen, then yes, it's probably fine.>
Or am I missing some component? I also neglected to tell you that I do have a 12" bubble stone for aerating, and that I use both the carbon filter sized for that 110,
<Carbon largely pointless in freshwater fishkeeping.>
plus a "50" size (smaller) ammo-rid tucked in with it ,
<Again, ammonia-removing media is usually pointless too.>
plus the foam and bio-max material. (I didn't care for the Zeo-Carb for some reason, but this combo seems to work well) That is probably helping to keep my numbers good (0 ammonia, 0 nitrite, I don't have the test for nitrate). Given the additional information, would you still consider it to be slightly overstocked (7 fantails, from about 1.5 - 3.5" body lengths)?
(and what about 6, read down a few paragraphs for why) And thanks for telling me not to bother with the salt; I had read elsewhere that a low amount of salt was beneficial for goldfish, but I'll just save my money and time on that one!
<Quite.>
I was interested to see in your FAQ and email about such substantial water changes; I guess I still have the mentality of 10% a week "freshens" things without disturbing the fish. I'll bump it up, now that they should be used to the higher pH at the new house.
<Yes.>
Per your reply, I put the fish back in the big tank, and he was quite happy for a few hours, but then started celebrating by chasing and nipping at everyone else, nonstop.
<Glad to see his friends.>
I watched him do that for an hour, and decided to put him back in the quarantine until I can set up a 29 for him to live in splendid isolation, given his nasty behavior. That does, however, explain the occasional ragged fin (shaped like a bite mark) that I had seen in the past on the others. He was just never so blatant about it that I caught him at it before; guess he was making up for a month's worth of lost aggression. (I did try shaking my finger at him and saying "bad fishie", but it just didn't have the effect that I desired). I do thank you again for giving me the go-ahead to stop being worried about the bump on him.
<Does sound as if you've established the problem here. Males develop distinct spawning tubercles on their heads at breeding time. Such fish are often "chasers" or "bullies" for a few weeks, months around this time of year.>
Best regards, and have a great week, and summer solstice!
<Thanks, and you too.>

New Betta...Help! Not eating, env., Lernaea 5/3/11
Hi There-
<Shanda>
I am hoping you can help me with my new Half Moon Doubletail Betta. I bought him from Petco 11 days ago and when I first got him home he was very energetic but has never been willing to eat.
<!? Is this system heated, filtered?>
I know that they can be picky eaters so I have tried a couple different brands of food. I previously had a Betta for over two years that finally died a few weeks ago. He loved the Hikari pellets so that is what I have tried to feed the new fish. He initially swam up ate it and then spit it out. I tried again the next day and the same thing happened. I went and bought Betta Min Tropical Medley and tried that. The fish swam up to it and then swam away. I have been trying every day and the fish swims up like it is hungry and then swims away. I tried crushing the pellets thinking that maybe they were to big but he eats them and then spits them out. I have noticed over the last 2 days that he seems lethargic and he looks like he his starting to float on his side. I have also noticed him with his nose to the top of the water (straight up and down). I have been scooping out the uneaten food so that his water doesn't get contaminated. Today a friend of mine gave me dried blood worms to try and the fish swam up and looked at them and swam away.
He is in the same tank that my old Betta loved. It is a gallon bowl with rocks and a plant.
<...>
I used Aqua Safe for the tap water and added a drop of stress coat to it. I got a thermometer and it said it is between 72 and 75 degrees. Not sure what else to do. Any suggestions?
<Read here: http://wetwebmedia.com/FWSubWebIndex/bettasysart.htm
Thanks so much for you time!
Shanda
<Welcome>
P.S. I have attached a picture. He also has these little white things hanging from his bottom fins. Is that normal?
<Mmm, no; these are anchor "worms". Read here re: http://wetwebmedia.com/FWSubWebIndex/anchorwrmfaqs.htm
Likely contributing to this fish's troubles, non-feeding. Bob Fenner>

Re: More re: New Betta...Help! Lernaea 5/3/2011
Thanks so much Bob!
There is so much information on here so I am hoping I am reading correctly.
This is what I am thinking that I need to do....please let me know if I am incorrect. =)
<Okay>
I need to take the fish out of water and carefully remove the white anchors with tweezers (grabbing it right at the entrance spot) and then dab the wound with Mercurical.
<Yes>
I am a little unclear about what to do about the tank since it is a small tank. I am thinking I need to wash the bowl and throw out the gravel, put new gravel in, treat the water with stress coat to take out the chlorine and then add some aquarium salt???
<Mmm, no... I'd wait, see if any intermediate forms have been released by the adults on your Betta. Perhaps they haven't>
Also, should I throw the plant away or just wash it? I know the parasite was on the fish when I bought it. I am hesitant to take it back to the store because they probably won't even bother to treat it. I am praying that I can fix him.
Again, thanks so much for your time. Your website is so helpful!

<Did you read re Betta husbandry, where I referred you? Your fish needs warmer (steady, as in w/ a thermostatic heater) water and a filter. BobF>

My fish have splinters!!! 12/29/10
I have two three goldfish in a 10 gallon tank. I taking them out of the tank yesterday to clean it and I noticed that the smaller goldfish had splinters (or maybe bones?) growing out of him/her. I checked the other two and they also have them but not as much. I tried to take them out with some tweezers but I couldn't and the splinters were hard like maybe bones. I have no idea what it is or what to do. Can anyone please help me.

White Worms on Goldfish 11/7/10
Hello, I have a question about white worms on my goldfish. I've searched the site--thank you for all the information and help you provide, but am not finding cases that are similar to mine. I have a 55gal planted goldfish tank with 5 fancy goldfish, 1 Oto and a handful of Nerite snails. I do 40% water change weekly, the basic water parameters are; ammonia=0, nitrite=0, nitrate<20, pH 7.4, tamp 70. 2 of the fish, cute Ranchus, are new--they were introduced to the tank a little over a month ago. The smaller Ranchu at about 3-1/4" has had white worm looking things on his body and fins after she joined the family. These worms are white and thin, about 1/16" or less in length, and they look like short white threads or small white stitches on this Ranchu's body and sometimes fins. Some of them come and go (or move around, I'm not sure) over night, and some stay on the same spot for days. My first impression was that they were small Planaria that attached themselves to the fish, although I've never read any articles stating Planaria can attach themselves to fish. I've seen Planaria in my tank water and walls from time to time, but I've always thought they were free swimming worms rather than parasites. My orange fantail (largest and gorgeous fish at 6") used to get a few of the same thing on his body/fins occasionally, but with him they always went away after a few days. I'm starting to get worried for the little Ranchu if this is in fact a case of parasitic infection and she is not able to shake it off on her own. I was told by the supplier of these Ranchus (dandyorandas.com) that they were treated with Prazi while in his care. Additionally, they had a ParaGuard/salt bath upon arrival, and they were fed Jungle Anti-Parasite Medicated Food (Metronidazole 1.0%, Praziquantel 0.5%, Levamisole 0.4%) for a full course of treatment according to the instruction. I'm not able to get any clear pictures since the Ranchu is active. She eats well and appears happy otherwise, no obvious signs of distress or flashing. My only concern with her is that she is currently the smallest fish in the tank, and the more I worry, the more it seems as her scales are rather rough and lacking luster compared to the others. Do you have any idea what I'm dealing with, and do you suggest any further treatment? Thank you in advance for your help, I look forward to hearing from you. Yuko
<Hello Yuko. I'm fairly sure you're dealing with Anchor Worms, Lernaea spp. Although not common on Goldfish kept indoors, they do occur from time to time, and may persist for months or even years unnoticed at very low densities. There are commercial medications for removing Anchor Worms. Do also read here for more: http://www.wetwebmedia.com/fwsubwebindex/anchorwrmfaqs.htm Do note that despite being called "worms" these aren't worms but crustaceans, kind of in the same way koala bears aren't bears. So medications like Praziquantel might be used against true worms, they're useless for treating Anchor Worms. Cheers, Neale.>

Anchor worm on Synodontis catfish? 8/7/10
Hi,

<Hello,>
There is what looks like a worm buried into the side of my Synodontis catfish.

<Oh?>
It is white and attached at both ends giving the appearance of a small, white staple, so I can't see a forked end to positively identify it as an anchor worm, but I don't know what else it would be.

<There are various similar parasites of this type beyond Anchor Worm, and wild-caught fish do sometimes bring them along when they're caught.>
It is about 1/4 inch long (the part that is visible, that is.). There has been nothing (plant or animal) added to the aquarium for probably a year.

<Has this "worm" not been visible in the last year?>
No live food is used. Can you please help with what it might be and how to treat it, given that she is a (very sweet!) scaleless fish?

<Assuming this is Anchor Worm, and we need a photo to be sure, treatment in this case is going to be two-fold. Firstly, you need to physically remove the worm. Use forceps or tweezers for this, and be incredibly careful. Restrain the catfish with a wet towel. Don't rush -- the fish can handle being out of the water for a good few minutes so long as its wet -- but thrashing about is going to damage you and the fish. Remember, catfish are equipped with sharp spines and WILL NOT hesitate to use them, so don't allow your fingers to get between the spines and the body or the fins will clamp shut and cut your fingers nastily. After removing the worm, dab with a little antiseptic; iodine for example would be ideal. Use a cotton swab for this. Removing the worm opens the fish up to a secondary infection, so the second step is to prevent that. Use either a broad spectrum antibiotic or some sort of mild antibacterial such as Melafix.>
Thank you, Constance

<Good luck, Neale.>

goldfish - spot turned into a spike, Lernaea likely 7/28/10
Hi. I hope I am not wasting your time, but I can not find what I am looking for anywhere on the internet. I have a very dark goldfish, almost black, and had him/her in a quarantine tank on it's own for several weeks. I bought it at the local aquarists, where I have previously purchased a tench that had mouth rot and died within a week or so. I should have learnt my lesson and not gone back. The black ones were not selling in their tank and were getting big, so were being sold cheap. Thing is, as the pond fish are sold, more fish come in and they go in the same tank/water, as far as I can tell. I thought that as this black one was big it must have been there a long time and so disease free.
<Mmm, "shop" goldfish are typically festooned with good parasite counts>
It must be around 6 inches including a large flowing tail.
<Likely a "comet" variety... will get bigger if it lives>
Within a day or two of getting it home I could see that it had 2 very pale whitish spots on it's mouth, one on the upper lip and a smaller one on the lower, around 1 to 2mm diameter.
<Could be "just colour">
I didn't really think much of it as the fish has a pale belly, and as nothing seemed wrong I assumed it was just it's colour pigmentation. I have had him at least a month now, and had recently put him into a tank with other goldfish, for observation before release into my pond. So, I was considering freeing him into my pond outside last night, but when feeding him first, I noticed that the spot on the upper lip had formed a spike, very very small, less than 2mm long. It looked like something was protruding from the white area of the white spot, maybe in place of the white spot.
<Mmm, any chance of sending along a well-resolved image of this area, spike?>
I have had goldfish with worms before and have a bottle of Prazi pro
<Mmm, not useful here... as this is likely a "crustacean" parasite... Lernaea, Anchorworm>
in my store cupboard. I have gave him a dose of this, about 24 hours ago, but am really unsure if this the right treatment as I am so far unable to identify the disease, or parasite. I have looked at pictures of anchor worms,
<Oh!>
but I don't think it is this as the 'thing' has not attached itself to the fish, but grown outwards from within.
<This is the life cycle... and do look like "spikes" starting out>
Now I have just caught him into a small transparent box (while emailing you) to have a better look at him, and the white thing seems to have gone, and in place of both the white spots are pinkish bits, looking a bit like pin-prick holes.
<This too can be indicative>
Could the white things have 'gone back in', or come out, or been killed by the treatment?
<Maybe the latter, but I would still treat the system (all fishes in contact) with an organophosphate>
While in this small observation box I have noticed streaks of red in his fins, obviously signs of stress. I wonder if you are able to tell me what this parasite is and whether I may have cured it as I am anxious to get this fish back into a better environment as I don't like to think that it is stressed/diseased.
Obviously may aim is to be able to free it into my pond. Also, should I treat the other fish it was temporarily housed with, I have been reluctant to do so as this larger tank houses snails which I do not want to kill. I do not know if Prazi pro will kill snails.
Any help much appreciated.

Re: goldfish - spot turned into a spike 7/28/10

Many thanks for your reply and for the links.
Anchor worm is a lot nastier than I thought !!
<Yes... not to be/appear too reverse anthropomorphic, but OUCH!>
After e-mailing you last night, and as the thing(s) had appeared to have dropped off with the use of Prazi pro, I removed all the snails from my big tank containing the fishes pending to go into my pond, and stripped out the gravel and did a thorough clean down, 30% water change, and added Prazi pro to them as well. There are no signs of any health problems with these fish, and I can not find out how long I need to keep an eye on them before I can be sure they are parasite free and OK to release outside. Can you tell me?
<A few weeks>
Thank you for your comments suggesting organophosphates, which I have researched this evening, to find are not available in the UK. I remember I had to order the Prazi pro on the internet from abroad (US I think) as it was not available here, this was a few years ago now, but I can not find anywhere that will ship Dimilin or similar to the UK either.
<I encourage you to ask among your stockists... and/or a Vet. re>
I am keeping a close eye on the dark fish, which appears no different tonight than last night. I have tea tree and salt in my store cupboard, and wondered if these would be of use to fight any infection that may grow due to the holes.
<Not really, no. More likelihood of exacerbating problems by increased stress, decreased biofiltration with their use>
How long should I leave the fish in the Prazi pro treated water?
<... I don't think this vermifuge will do any real good here, but three-four days finds the compound losing potency>
- (And is the possible dropped off thing still alive and able to hop back on?)
<No... but if there are some present on the fish, there may well be intermediate forms in the system itself... Hence the call to remove adults (via tweezers) and treat the water/system>
- as I would like to get him out and into a bigger less stressful space. He is in about 4 gallons at the moment.
<Put in the tank, treat all>
Also, on reading about organophosphates I read they are not suitable for Orfe or tench.
<Are to degrees toxic and tolerable to all>
I have both in my pond, and Orfe in the potentially infected tank. It is likely also that I have released into my pond already, fish that were previously in my tank when for a short while the sick fish was present.
<Ohhhh>
Would the parasite, if it is anchor worm, have been at a contagious stage when I first purchased him, with the only signs a couple of pale spots?
<Possibly, yes... the egg-bound females are quite a bit larger, more obvious>
After a few weeks he went in with the other fish in the big tank for a few days, and then I took some of the fish that were present at that time, out, and released them into the pond. And I thought I was doing such a good job at Quarantine! Still a novice - I have kept pond fish for about 7 years.
I can take some pictures if it would be helpful, but there is no spike to see at the moment.
Thanks for your help.

<... yes>
I have been searching for ages for treatment available in the UK for anchor worm, and eventually found this, from
Waterlife, and available on eBay.
I have purchased a tub of tablets, with which to treat the black fish, he is still in isolation by the way. I didn't want to return him to the rest as none of the others have shown any sign of any problem at all ever. I will play the waiting game and just 'see', before they go in the pond. And I will have the tabs with which to treat any future problems. All this trouble began as we were building a bigger pond. I moved all my old fish from their old home, 100 gallons small pond in the front garden, to new home 600 gallons formal pond at the back. Then I decided I did not have enough fish, and bought a couple at a time, mostly small, that have lived in a tank in the house while being watched/quarantined and while growing bigger ready for release. As my small pond is empty other than original plants and water, pump still flowing, etc, I an now thinking of releasing the dark fish into that, where he will have more room, can still be observed, and I can treat him safely alone with the Parazin P when it arrives. I guess I have been lucky that I have had enough tanks/ponds to hand, and already had a spare filter in the main tank etc. I do take try to take good advice on board, ready for those 'in-case' occasions.
<Real good>
I have just caught him again for a few pictures. See attached. There is no spike, but it is clear in at least a couple of these, that there are pinkish patches, that today look less like holes - one on the top lip and one on the bottom. During taking these I noticed a pale blob on his face, left hand side below his eye and just forward towards his mouth, again about 1-2mm.
I took about 20 pics, but could not get this blob to show up. I am sure this was not there when I last looked up close, 2 nights ago. I am sorry these photos are not clearer, but you can see their size - the fish is around 6"
nose to tail. Do you think this is anchor worm?
<Can't tell>
I hope you don't mind me asking you look at another fish picture. When moving my fish from the small pond to the larger one I found one of the original fish I had around 7 years ago. Very slim, Orfe in shape, brownish on top with red fins. I rarely see him in the pond as he is nearly invisible, but I was surprised and pleased to see he is still going, alive and well, though surprisingly small for his age, maybe 5" long. The orfes I have grown rapidly in this time, and are always at the surface. Are you able to identify this fish for me?
<No>
Thanks once more for all your help.

goldfish - spot turned into a spike, Lernaea likely 7/28/10
Hi. I hope I am not wasting your time, but I can not find what I am looking for anywhere on the internet. I have a very dark goldfish, almost black, and had him/her in a quarantine tank on it's own for several weeks. I bought it at the local aquarists, where I have previously purchased a tench that had mouth rot and died within a week or so. I should have learnt my lesson and not gone back. The black ones were not selling in their tank and were getting big, so were being sold cheap. Thing is, as the pond fish are sold, more fish come in and they go in the same tank/water, as far as I can tell. I thought that as this black one was big it must have been there a long time and so disease free.
<Mmm, "shop" goldfish are typically festooned with good parasite counts>
It must be around 6 inches including a large flowing tail.
<Likely a "comet" variety... will get bigger if it lives>
Within a day or two of getting it home I could see that it had 2 very pale whitish spots on it's mouth, one on the upper lip and a smaller one on the lower, around 1 to 2mm diameter.
<Could be "just colour">
I didn't really think much of it as the fish has a pale belly, and as nothing seemed wrong I assumed it was just it's colour pigmentation. I have had him at least a month now, and had recently put him into a tank with other goldfish, for observation before release into my pond. So, I was considering freeing him into my pond outside last night, but when feeding him first, I noticed that the spot on the upper lip had formed a spike, very very small, less than 2mm long. It looked like something was protruding from the white area of the white spot, maybe in place of the white spot.
<Mmm, any chance of sending along a well-resolved image of this area, spike?>
I have had goldfish with worms before and have a bottle of Prazi pro
<Mmm, not useful here... as this is likely a "crustacean" parasite... Lernaea, Anchorworm>
in my store cupboard. I have gave him a dose of this, about 24 hours ago, but am really unsure if this the right treatment as I am so far unable to identify the disease, or parasite. I have looked at pictures of anchor worms,
<Oh!>
but I don't think it is this as the 'thing' has not attached itself to the fish, but grown outwards from within.
<This is the life cycle... and do look like "spikes" starting out>
Now I have just caught him into a small transparent box (while emailing you) to have a better look at him, and the white thing seems to have gone, and in place of both the white spots are pinkish bits, looking a bit like pin-prick holes.
<This too can be indicative>
Could the white things have 'gone back in', or come out, or been killed by the treatment?
<Maybe the latter, but I would still treat the system (all fishes in contact) with an organophosphate>
While in this small observation box I have noticed streaks of red in his fins, obviously signs of stress. I wonder if you are able to tell me what this parasite is and whether I may have cured it as I am anxious to get this fish back into a better environment as I don't like to think that it is stressed/diseased.
Obviously may aim is to be able to free it into my pond. Also, should I treat the other fish it was temporarily housed with, I have been reluctant to do so as this larger tank houses snails which I do not want to kill. I do not know if Prazi pro will kill snails.
Any help much appreciated.

Re: goldfish - spot turned into a spike 7/28/10

Many thanks for your reply and for the links.
Anchor worm is a lot nastier than I thought !!
<Yes... not to be/appear too reverse anthropomorphic, but OUCH!>
After e-mailing you last night, and as the thing(s) had appeared to have dropped off with the use of Prazi pro, I removed all the snails from my big tank containing the fishes pending to go into my pond, and stripped out the gravel and did a thorough clean down, 30% water change, and added Prazi pro to them as well. There are no signs of any health problems with these fish, and I can not find out how long I need to keep an eye on them before I can be sure they are parasite free and OK to release outside. Can you tell me?
<A few weeks>
Thank you for your comments suggesting organophosphates, which I have researched this evening, to find are not available in the UK. I remember I had to order the Prazi pro on the internet from abroad (US I think) as it was not available here, this was a few years ago now, but I can not find anywhere that will ship Dimilin or similar to the UK either.
<I encourage you to ask among your stockists... and/or a Vet. re>
I am keeping a close eye on the dark fish, which appears no different tonight than last night. I have tea tree and salt in my store cupboard, and wondered if these would be of use to fight any infection that may grow due to the holes.
<Not really, no. More likelihood of exacerbating problems by increased stress, decreased biofiltration with their use>
How long should I leave the fish in the Prazi pro treated water?
<... I don't think this vermifuge will do any real good here, but three-four days finds the compound losing potency>
- (And is the possible dropped off thing still alive and able to hop back on?)
<No... but if there are some present on the fish, there may well be intermediate forms in the system itself... Hence the call to remove adults (via tweezers) and treat the water/system>
- as I would like to get him out and into a bigger less stressful space. He is in about 4 gallons at the moment.
<Put in the tank, treat all>
Also, on reading about organophosphates I read they are not suitable for Orfe or tench.
<Are to degrees toxic and tolerable to all>
I have both in my pond, and Orfe in the potentially infected tank. It is likely also that I have released into my pond already, fish that were previously in my tank when for a short while the sick fish was present.
<Ohhhh>
Would the parasite, if it is anchor worm, have been at a contagious stage when I first purchased him, with the only signs a couple of pale spots?
<Possibly, yes... the egg-bound females are quite a bit larger, more obvious>
After a few weeks he went in with the other fish in the big tank for a few days, and then I took some of the fish that were present at that time, out, and released them into the pond. And I thought I was doing such a good job at Quarantine! Still a novice - I have kept pond fish for about 7 years.
I can take some pictures if it would be helpful, but there is no spike to see at the moment.
Thanks for your help.
Wendy
<Let's wait, hope that all is to be well at this point. Cheers, BobF>
Re: goldfish - spot turned into a spike 7/29/10

Thanks.
I am very impressed with your site and the amount of information available to those needing help! Also with the speed of replies - fast help when it is most needed. :-)
<... Wendy... you've sent 13.5 megs of ill-resolved, worthless images... we don't have space for more than a few hundred Kbytes... which is what we ask people to limit theirs to>
Have you heard of parazin P ??
<... yes>

Waterlife, and available on eBay.

Re: Hi, Guppy, Lernaea, reading - 03/30/10
Hi, thanks for the help that you have given me few weeks ago, I see that some of my fish's health are improving. I also found a pair of anchor worms in one of my female guppies (V shape from her bottom).. I pulled one out with a tweezers.
<Yowch! Easy to kill such small fishes with such extraction>
but still am trying to pull the other one out..not sure why but that other anchor worm keeps going back into her body when I fish her out to try and pull it out.
<Umm, their name is a hint>
So far that guppy is in quarantine...
<Still need to treat the main system to eradicate the young Anchorworm crustaceans there... lest they develop, infest your other fishes>
I removed all fishes that looked sick into a separate tank (each). Any other ways to treat that guppy with the anchor worm or I have to just wait for it to come out and try again till I succeed?
<Read here: http://wetwebmedia.com/FWSubWebIndex/anchorwrmfaqs.htm
and the linked files above>
Back then a couple of my male guppies have problems opening their fins because of fungus. Right now though...although their fins look fine now..I notice that one of the male started developing something that looks like
black patches around the fins and tail...I attached the best picture that I can take..Hope it helps.

Calico Fancy Tailed Gold Fish, Lernaea, more hlth. issues 11/24/09
Hi Crew
<Hello,>
Please could you help?
<Will try.>
I purchased a Calico, Red Cap Oranda Gold Fish 18 days ago. He is about 14 centimeters in length.
<Good size!>
He was put into a quarantine, when purchased. Its a 40 liter tank and all basics in water quality have been checked and are good.
<Good? Not in a 40 litre tank they're not. Seriously, this tank IS TOO SMALL for a Goldfish this size. Indeed, it's too small for a Goldfish of any size. I cannot stress this point too strongly. Minimum aquarium size for Goldfish is around 110 litres.>
On close inspection when I got his home I discovered he had 3 anchor worms.
I am treating with Parazin. First treatment of 14 days released 2 of the worms. (I did a 50% water changed after completion of the first 14 day treatment), waited 48 hours, and now have added a second table of Parazin, for a second 14 day treatment to try and rid him of the one stubborn anchor worm. I have also added 1 teaspoon of salt, per 2 liters of water.
<Okay.>
My concern is he also has two dark black foreign clumps of matter, (Never seen this before) about 2 mm in size, embedded into his Wen, both, just above his right eye.
<Black specks on Goldfish are typically ammonia burns. They can be caused by other types of physical damage, but ammonia burns are the most common.
Because the aquarium is so small, I have little doubt that water quality is either the direct cause or aggravating whatever background problem there might be.>
These were present when I bought him, don't seem to worry him and have not changed is size, colour or shape, over the 18 day period. There are no other visible signs of these black crustaceans anywhere on his body. It is more visible with the first 2 days of treatment of using the Parazin, as the flesh directly above these spots, seem to open up a little, giving a visual of the dark black spots embedded into the skin. They are berried about 2mm into the skin. By day 3 of the Parazin treatment, the (Hole) tiny opening seems to close, and the black spots are once again covered by the flesh of his Wen and look like dark black shadows, under his orange Wen, almost undetectable.
He is eating well, has a varied diet of green peas, bloodworm, daphnia, flake and pellets, and on the whole, looks pretty healthy, swimming actively with his dorsal fin extended.
Do you have any idea what this would be? and what and how I could treat it.
<Do read here:
http://www.wetwebmedia.com/FWSubWebIndex/goldfish101art.htm
Almost all problems with Goldfish come down to people keeping them badly.>
Your assistance is appreciated ....
Many Thanks

PLSS HELP - Something wrong with my Flowerhorn - Unable to diagnose. Env. -- 09/08/09
Hello,
<Hi there>
Something definitely wrong with my Flowerhorn... I will try to be as descriptive as possible..I have not given any pictures in this post.. because picture in this case will not tell you anything...
Background
Tank - 48 X 18 X 18
<In inches I'll take it, not cm.>
Filter - Canister 1200 L/H
Air Curtain for aeration...
Small pebbles in the ground, not as a substrate but more of him to play with...
<At times gravel is useful to necessary to foster biological filtration>
A bog wood - on which the air curtain is tied around
Sunday (August 30th 2009) - Performed a major cleaning of his tank. Cleaned glass, he had quite few number of pebbles as gravel to play with, had to remove some of them, because they were very dirty.. Cleaned the canister medium only partially... changed water over 50%...
<Mmm, I would usually keep such changes to 25-20% maximum>
Wednesday (2nd September) - Got hold of a brand new packet of Ching Mix Sp100 (from US) - Started feeding him in small quantities morning and evening..
Thursday (3rd September) - Noticed an unusual thing in the evening.. FH has passed poo usual in color, but the poo was floating on top of the surface instead of settling down..
<Can be just the food>
Problem
Friday (4th September ) -
Morning - Changed water 20%.. added salt..
<... why? What sort of salt/s? Unless added to raise dKH or such, not necessary or advised with Neotropical Cichlids>
usual appetite for him and usual aggression.. he had his feeding (Ching Mix)
Evening - Went home to see him lying on corner of the tank.. color darkened.. The whole tank is spread with this Poo.. very unusual for a FH poo.. not continuous, but small granule like structure, black in color spread all across the tank floor...
Performed water change once again, cleaned the mess and added salt.... felt that he also had trouble in swimming... (is that a swim bladder??)
<...? No>
Saturday (5th Sep) -
Morning - Color improved... no signs of stress, but most of the time resting down...when swimming, swimming is normal.. tried showing him his food packet.. he became excited for feeding.. did not fed him though - Diagnosis, may be minor constipation... Stomach slightly bloated..Thought I should be stopping Ching Mix...
<I would>
Evening - Situation remained same.. Throughout this day, he did not passed any poo...
On account of heavy rainfall where I live...temperature of the tank was showing 27.4 degrees, Changed water 20%, added heater, salt, had set the temp to 30 degrees.. Did not fed him for the whole day...
Sunday (6th Sep) -
Morning - Still no sign of improvement.. most of the time resting below, he comes up only when someone approaches his tank.. But he had appetite...No food... Water change 20%, added salt
<Don't add salt>
Evening - Situation remained same...resting down.. not passing any poo... Tried him 1 pellet soaked in water.. I had to find out what was wrong... he ate that single pellet literally gulped it (Hikari cichlid staple)... Moment after consuming the pellet, vertical black stripes appeared out of no where and he went down to rest in the corner...
Monday (7th Sep) -
Morning - found him resting below, color darkened.. Started Metronidazole treatment... Metrogyl 400 mg dissolve in luke warm water, pellets soaked in that solution for 15 min.s.. fed him.. usual appetite, usual aggression while feeding... once completed, body turned black.. went down to rest...
Evening - Went home, found him resting on a corner.. he has passed Poo - this time normal in structure but dark yellow in color? When someone approaches, he swims fine... otherwise whole day resting in a corner - Stomach bloating disappeared...
Water change 20%, added Salt
<...>
Tuesday (8th Sep - Today) -
Morning, same situation resting, dark stripes in the body... fed him few pellets with Metrogyl soaked... He has passed Poo, small in quantity but dark yellow in color
Help me guys what is going wrong??
<Salt... water quality likely, some toxicity...>
1. Looking at his swimming pattern - he does not have a swim bladder...
<... Cichlids do have such>
Sometimes he jumps to catch the pellet..
2. Internal Infection - He is not passing any white poo
3. Stomach is not bloated...
4. Immediately after food, the dark stripes come in, remains for some time and then disappear..
Does he have a internal blockage???
<Doubtful>
One point wanted to mention here -- The bottom edges of his tank is covered with some kind of a yellow/white film which I thought was water mark on silicon gel..The fellow who prepared this tank had actually emptied 1 full silicon gun on my repeated warnings of leak...
<... When was this done? What sort of Silicon/Silastic was used? Some has mildewcide in it... for window use... is toxic. Could be at fault here>
This yellow/white kind of things keeps coming out from those edges, specially when i change water or when there is a turbulence... some part gets sucked by the canister, some again settles in the bottom...
Since yesterday I am also observing the same kind of this thing is hanging from this dorsal fin.. ?? Is he also having an fungal infection?? This is a new symptom came out of no where
Some ideas friends --- I am fearing, that I should not be late in corrections.. he still has appetite for food... if he looses that, then the damage would be done already...
Regards
Nimo
<Do get hold of the Silicon cartridge, read what the intended use is. Bob Fenner>

Re: PLSS HELP - Something wrong with my Flowerhorn - Unable to diagnose Lernaea? 9/10/09
Hi Bob,
<Subhankar>
First of all thanks for stepping in to help me out
<Sure>
Update on the situation...
Yesterday I had first roller coaster ride in my 10 yrs of hobby..
The diagnosis was wrong..
I observed him sulking in a corner in a slanting position.. I observed him lethargic, I observed him turning dark in color.. so the first idea which anyone gets is an internal stomach problem...
But the confusion was
1. He had the usual appetite
2. His stomach was not bloated
3. He was passing poo normal in color
Tuesday (8th September 2009)
Evening - I observed whenever he sulks, he sulks in the same position in whichever corner of the tank he chooses... He sits in a posture where both his pelvic fins are covered in the ground, I also observed that he has a very mild movement pattern sitting in the same position, as if swinging like a pendulum...
I observed he had two red scars in his pelvic fin and a pure white thread like structure 1 inch in length hanging from both the scars - Worst part is that thread has a sac like structure or a ball at the end....
Wednesday (9th September 2009)
Morning - Saw the thread like structure has disintegrated from one of the scars, one still has a reminent, very small in size..
Three new white pimple like structure arrived on his tail.. they were new... looks like some kind of a white pimple...
Afternoon - My all doubts were Anchor worm, ...
<Ahh! A too-common parasite for pond-raised fishes, or kept with, fed fishes from...>
I had seen this before with one of my friend's goldies, So i knew how does an Anchor worm look like so, at the same time was not aware of what is the commercially available medicine, whether will get it in shorter time.. from anywhere..
He was always sitting in bottom, in a posture, which used to cover both of his scars.. and he used to move some time to and fro as if rubbing those scars...
Decided to go for KMNO4 (PP) treatment..
<Mmm, not for Lernaea... Better the organophosphate route... DTHP or Dimilin... Please read here re: http://wetwebmedia.com/FWSubWebIndex/anchorwrmfaqs.htm
and the linked files above. You will need to extract/remove the adults on the fish itself with tweezers>
Had a 23 litres tank - dosage of 10mg/litre of PP, prepared a PP concentrated solution (25 mg in 500 ml of distilled water) and had put 5 ml of that in the 23 litres tank resulting in 230 mg of PP...
<Potassium permanganate is too strong an oxidizer for "casual use"... too easy to serious burn fishes>
Transferred the FH into that tank, and allowed him to be there for 20 minutes with heavy aeration...
By god's grace he took the treatment well.. he was swimming.. all through the treatment... there was heavy bubbling inside the tank.. the clean water of PP was filled up with very small disintegrated particles....
After 20 minutes took him out to a freshwater tub...
Cleaned his hospital tank thoroughly, filled - refilled twice,, and had put him back again....in his small hospital bed
<Good>
Then came the easy but the most tedious part.. had to again disinfect his 300 litres tank with KMNO4... this time did not measured the KMNO4 amount.. just poured it liberally in the tank with all decors inside... allowed the tank to sit for 30 minutes.. with PP solution...
<Yikes... stains most all. I would have used hypochlorite/chlorine bleach... Per the protocol detailed on WWM>
Then cleaned all his decor, refilled and cleaned 300 lites twice, till i was sure not a trace of KMNO4 was visible... poured it up with water, dechlorinator, salt started heavy aeration for 4 hours.. then transferred him back to his main home..
Immly he became white, all colors gone.. fed him two pellets, switched off the lights,
Thursday (10 th September) - today morning
Colors got back to normal...he ate pellets, active than before but still relatively lethargic..
<But... did you remove the adult Anchorworms/Crustaceans from the fish?>
Out of 5 pimples, 2 have vanished, 1 still exists, remaining 2 has very slight traces.. I am just hoping, that those are dead by now and would vanish in 2 - 3 days time..
I will be keeping a close watch on him...
Now the million dollar question i have, is how did this thing entered in my tank..
On last Sunday (30th Sep) - I did a major cleaning of both of my 4 feet tanks.. Till now i do not see anything to my Malawi Setup.. but the FH got affected..
I had kept him in a very good condition - I know difficult to believe, but people who have seen him as regarded my tank as one of most clean ones..
but still ...
I just hope that I am done.. and these remaining small spores would go away with Salt and temperature and I do not have to treat him with PP once again...
Had to do this, because these damn freaks were sucking all that I was feeding him...
Just hope he pulls through...
<Me too>

Dalmatian Molly, dis.; was: platies 8/27/09
Thank you again. I have another quick question about my Dalmatian molly.
She is about 2 months old or so and has developed this whisker like thing on her "nose". It looks stiff and about 1/8 in. long or so it actually splits into 2 but comes from one spot on top of her "nose " area. Is this
something to worry about - a parasite or just an abnormal growth.
<More than likely dead skin, and as such, a possible precursor to Finrot.
In the case of Mollies, the number-1 cause of such problems is keeping them in the wrong environmental conditions. Mollies do best in hard, basic water with a little marine salt mix added, around 3-6 grammes per litre being ideal. Marine salt mix (as opposed to the largely useless "livebearer salt", "tonic salt", or "aquarium salt" on sale) contains not just salt but also minerals that harden the water and raise the pH. The overall effect is to create slightly brackish conditions that suit Mollies extremely well.
Whilst Mollies are found in freshwater habitats for the most part in the wild, and less often in brackish and marine habitats, for whatever reason, they do best in saline conditions when kept in captivity. There are several explanations about this, but the most probable answers are to do with the stable basic pH and the reduced toxicity of nitrite and nitrate in salty rather than freshwater conditions. If you read through our Molly disease FAQs, you'll see this issue comes up again and again, and the only explanation can be that people buy them before reading any books first: practically every aquarium book written since the dawn of time has stated clearly that Mollies prefer slightly salty conditions. Anyway, my advice would be to add marine salt mix (e.g., Instant Ocean, or whatever generic marine salt mix brand your pet store sells) at the dose suggested above.
Other livebearers won't mind this, and in fact are likely to be healthier, particularly Guppies, though Platies and Swordtails aren't from brackish water habitats and won't appreciate the addition of marine salt mix above 6 grammes/litre. At this dose, you'll find using marine salt mix very economical: you're using about a sixth the amount used in marine tanks, so a box suitable for 20 gallons of marine strength salt water will make 120 gallons of water for a Molly aquarium. Most hard water tolerant plants will adapt fine, but most freshwater fish will not, but then, as is clearly stated on WWM numerous times as well as in practically every aquarium book ever written, you don't keep Mollies in community tanks. They aren't community fish, and never have been. The fact they often need saline conditions simply makes them untenable for such systems, though they work brilliantly well in livebearer, brackish water, and even marine community
tanks. I'd even argue that Mollies are such beautiful fish, and in the cases of Sailfin Mollies, so very large when properly cared for, that they amply deserve a tank all their own.>
She eats and acts fine with no other signs of distress. Thanks for your time. Donna
<Cheers, Neale.>

Re: Dalmatian Molly; was: platies. Dis., Lernaea? 8/29/2009
Hi Neale,
I found that not only does the molly have this thing but one of the baby platies has one hanging from it's bottom. I thought it was feces. At closer observation it looks like a Y comes from one spot and splits to a y
shape. I have gotten the salt - should I just continue with that and nothing else? I also had the water tested and it is fine. Again thanks for the input to a very novice aquarist.
Donna
<Donna, the shape is *strongly* suggestive of something like an external crustacean parasite. Google "anchor worms", "Argulus", and "fish louse" to see what you get. In general, these are best removed by [a] dipping the fish in a seawater solution (35 grammes non-iodised salt added to a litre of aquarium water) and then [b] forceps used to gently pull the parasite off. Maintaining the aquarium at SG 1.003 to 1.005 (6 to 9 grammes marine salt mix or tonic salt per litre) should also do the trick. If you're maintaining the tank as a brackish water aquarium, then raising the salinity using marine salt mix should shift the parasites, but if it
doesn't, then use forceps. Grip the parasite as closely as possible to the fish's body, holding the fish firmly without squeezing. Don't rush! If you dip the fish in seawater for one to twenty minutes, the parasite should
weaken, making this easier. Clean the wound with antiseptic (something like a dab of iodine or even Melafix) when done. Cheers, Neale.>

Re: Dalmatian Molly; was: platies, Lernaea 8/28/2009
Hi Neale
Yup that's exactly what it looks like when I Googled it.
<Very good.>
My concern is actually removing the thing. I'm nervous about taking the fish out and hurting it.
<May well "hurt" as you pull the thing out, but much less dangerous (or painful) than the constant sucking of blood.>
Is there anything special I need to do, do I just hold it in between my fingers?
<Not fingers; must be forceps, or something similar, like tweezers. Have you ever removed a tick from a dog? Not dissimilar; must remove whole thing, including mouthparts, taking care not to snap the body in two and so allow secondary infections. Your aquarium shop may sell certain Anchor Worm specific medications, e.g., Anchors Away, but these are often fairly toxic in themselves, and can harm sensitive fish (e.g., Loaches, Catfish) as well as invertebrates (snails, shrimps). They aren't always effective, either.>
I have the Melafix also - do I just apply only once after pulling it out or do I repeat that until the wound heals - or should I just add the Melafix to the tank after wards also. I do also have the stress coat stuff to add
to the tank for the slime - is that also suggested?
<I'd dab a little neat Melafix with a Q-tip onto the wound, and then dose the tank as suggested by the instructions. Stress Coat shouldn't be required, and in fact I recommend against mixing two or medications unless you know it is safe to do so.>
I was hoping that with the salt treatment it would fall off but of course it did not.
<How much salt did you add? At one extreme, if you transferred Mollies to a marine aquarium (or similar added 35 grammes marine salt mix/litre water) the Anchor Worms would quickly die. In a freshwater tank you can add up to a specific gravity of 1.005, or 9 grammes salt per litre, which should certainly weaken the parasites without harming salt-tolerant fish like Platies as well as Mollies. Of course, non-salt-tolerant fish may not accept such conditions for long.>
My other question is do I have to do anything else to ensure that the anchor worm is gone from the tank?
<There's no 100% reliable way, but usually removing the worms you see, and if any others occur afterwards, removing those, breaks the cycle.>
A 25% water change I'm guessing.
<Won't do much of anything against Anchor Worms, since these are attached to fish, not swimming about.>
Also is there anything I need else I need to do to ensure recovery of the fish?
<Usually the fish recover very well.>
I know nothing is "for sure" but I want to give it as good of a shot as possible. We haven't added any new fish - besides the babies - in quite some time I'm wondering how this parasite got in.
<Typically, Anchor Worms breed in ponds, and in the case of livebearing fish, this would have been outdoors on a farm in Florida or wherever.>
Any ideas on how not to get a re infestation?
<Observe new fish carefully, quarantine them, and if you see Anchor Worms, remove them before placing them in the main aquarium. Anchor Worms are actually pretty rare among aquarium fish, though they are more common on pond fish.>
Sorry for sooo many questions but as I've said I feel there is no better site than yours and trust everything you suggestion. Again thank you for your time and patience.

<Happy to help. Good luck, Neale.>

Re: Dalmatian Molly; was: platies, Lernaea 8/30/2009
Hello again Neale,
<He's marked "out till Tues.>
I added the salt as per the recommendation on the bag. Just to make it slightly brackish for the molly. We have all platies except for the one molly who we've had as a fry and who just appeared in our tank one day. We had an adult who had passed a while before hand due to ick but must have been pregnant. Anyway 2 adult platies, 2 platy babies ,one baby molly and a clown Pleco in a 29 gallon tank. All but one baby platy has an anchor worm. I will try removing the ones I see and let you know.
<Do take care here, with their extraction... the adults' removal can/does cause a great to mortal amount of damage. Read here:
http://wetwebmedia.com/FWSubWebIndex/anchorwrmfaqs.htm
and the linked files above; particularly re the use of organophosphates>
But as I stated before a bit worried about doing that. I was wondering how to hold the fish actually - with my fingers or laying him out on the net?
<The net>
Will this just stress them out?
<Will>
As you can tell a really new fish hobby. But if I don't ask I won't learn!
I really appreciate your time. I'm just wondering if the anchor worm has eggs and more develop - that was the reason I questioned about doing the water change.
Again thanks Donna

<Donna, Bob, just wasting time at CVG airport. Thanks for taking the time to answer this query, Bob. Donna, yes, removing lice is tricky but not difficult, and dipping in saltwater, as mentioned earlier, weakens the crustacean sufficiently that removal isn't hard. Will bow to Bob's better knowledge of organophosphate insecticides for treatment, but my understanding is that these have reduced/zero impact on "attached" lice. It
is telling that much research in aquaculture is towards "manual" removal via cleaner organisms; in the UK, the favoured "cleaner fish" on salmon farms being juvenile wrasse, analogous to cleaner wrasse behaviour in the tropics. Cheers, Neale.>

medication, Lernaea
Hi crew, a quick question about medicating my tank. I had medicated it for anchor worm - which didn't work
<... doesn't work on embedded adults>
so now onto pulling them out manually, but replaced the filter to get the medicine out. How long is this process because after I attempt to remove the anchor worms I was told to apple Melafix
<... no>
on the spots and treat tank with the Melafix for about a week. If I do that I have to take the carbon out of the filter. So I want to make sure all the medication is out first. Thanks for any input. D
<Depending on the quality of the carbon employed, the amount, volume of the tank, circulation through it... a few hours. BobF>

Re: Dalmatian Molly; was: platies, Lernaea 9/1/2009
Hi crew,
I removed the anchor worms with tweezers but not really sure if the head came with it.
<Is distinctive...>
I tried my hardest to get the fish still but of course one jumped as I was pulling and not sure if the whole thing came out. The anchor worms were all in uneasy areas (right next to fins and one by the mouth) and hope I didn't harm the fish, they are very hard to distinguish between when they are out of the tank everything is so translucent. They all seem shaken by the ordeal as I am also. If I didn't successfully remove the head can I say these fish will eventually die?
<Mmm, no; not necessarily>
I used the Melafix on them and am treating the tank with it also. Now just wait and see? I'm so upset by this whole endeavor. What else needs to be done? Thanks for your time and patience - kind regards Donna
<When, where in doubt, keep reading. B>

Re: Dalmatian Molly; was: platies, Lernaea 9/1/2009
Hello AGAIN,
I'm glad to hear that they may not die, I last spoke with Neale who suggested using the Melafix after wards is this a sufficient tonic for recovery.
<Ah, no, perhaps I wasn't clear. It is standard practise after physically removing Anchor Worms and other "skin biting" parasites to dab the wound with an antiseptic such as iodine. If you have Melafix, then this might be used in the same way, as a topical antiseptic, or perhaps added to the water to reduce the chances of secondary infection. In and of itself, Melafix won't cure Anchor Worms, and as Bob is intimating, Melafix isn't altogether reliable, and you may still find the wounds become sites of secondary infection, in which case an appropriate anti-bacterial or anti-fungal would be used.>
Is there a different solution? I got a different answer from Bob. Needless to say they are tight finned right now and not looking happy. I had put some Cycle in this morning - suppose to help with fish loss? Anyway I'll heed any info you throw at me. Have read all the FAQs about the anchor fish on your site but will take any other info if you have. Again thanks for your knowledge sharing! Donna
<Physically removing parasites from fish shouldn't cause undue stress,
<<!? Lernaea extraction I've seen cause outright death... being netted, handled, having a large (%) mass removed from the body, bleeding... RMF>>
and usually they recover quite rapidly from the stress of being removed from the tank and handled. The chances of secondary infection aren't great, but it does happen, hence the need to keep your eyes open for signs of bacterial or fungal growth. Cheers, Neale.>

Re: Dalmatian Molly; was: platies 9/1/2009
Hi thanks again, I see that most of the fish are back to normal from being on the bottom to up and swimming around and eating.
<Good.>
One in particular is swimming about at the top head up tail down clenched fins. Should I be worried.
<Yes, particularly if it doesn't show signs of improving over the next day or so.>
And lastly should I continue for the recommended 7 days with the Melafix in the tank or should I use the Cycle instead or along with the Melafix?
<Don't Melafix and Cycle do different things? Nutrafin Cycle is a largely useless product that is supposed to improve the performance of biological filters and (supposedly) speeds up the rate at which new filters become colonised by bacteria. I'd be surprised if it did much of either, frankly, but I'm sure of the many ways to spend money, it's among the more harmless.
So if you want to use it, go ahead, but it isn't going to make your fish healthier or a properly maintained and mature filter any better. Melafix is a tea-tree oil solution that has mild anti-bacterial and anti-fungal
properties. Some aquarists swear by it, but others, including Bob, are much more critical. I can certainly report that many aquarists who have used Melafix still go on to have bacteria or fungal problems, so at best, it's an unreliable "cure".>
cheers to you! Donna
<Cheers, Neale.>

Re: Dalmatian Molly; was: platies 9/1/2009
Ok cool I'll just use the Melafix - you know I'll always listen to you guys rather than the supposed fish experts at the LFS.
<I'm glad we can help.>
What should I do about the one I should be worried about - she's eating (a little) but no signs of anything on her body just the hanging out at the top and tail down.
<Is this a Molly or a Platy? With Mollies, fin-clamping is a common symptom of stress, sometimes to do with water chemistry or water quality, but sometimes because they're too cold. Oddly, while Mollies are subtropical to tropical fish in the wild, with a very broad temperature tolerance (they live as far north as the Carolinas in the US) the tank-bred forms need really warm conditions to do well, quite a bit warmer than the average community fish. So whereas Platies thrive best around 24 C/75 F, Mollies are usually better kept a bit warmer, around 26-28 C/79-82 F.>
The one and only male is definitely feeling better because he's "courting" her again and bothering her to no end.
<Clumps of floating plants will help.>
Didn't take long for him to be up and running.
<Indeed! Cheers, Neale.>

Re: Dalmatian Molly; was: platies... Lernaea f' 9/5/09
Hello,
I'm at a loss again they seem to be making a turn for the worst - hanging at the bottom and when they do come up for food their heads are up tails down. But they are eating. Any advice on what to do?
<Keep checking water quality, being observant>
Not sure of what's wrong. There are no visible sign of anything physical just that I extracted the anchor worms so could that be the problem? They are flashing on things too. Thanks for any advice. Donna
<Maybe. RMF>

Anchor worms and quarantine 6/4/09
Hi
<Hello,>
I've poked around on the web, but haven't found anything that can answer my question. On Monday I bought 2 new goldfish, a calico fantail (3cm) and a orange-and-white fantail (4cm), to add to my 10 gallon with a 6cm fantail (upgrading to 60gal at the end of the month).
<Glad to hear you upgrading this tank! Ten gallons isn't nearly enough for three Goldfish.>
I've had that fantail for a year and a half, with no problems. This morning (Thursday) I noticed that there are thin string-like things on the tips of the white-and-orange fantail's tail, he also has a scale that is dark (looks like a wound) that I noticed when I bought him home.
<Now, there are three things to think about here. The first is some type of external parasite like Anchor Worm, just as you suggest. But the two other things to consider are Finrot and Fungus. Finrot erodes fin tissue, leaving behind what we call fin rays (the bones) until these snap off. It's actually very common for Finrot to take the appearance of receding fins and trailing fin rays. Fungus is characterized by the presence of the hyphae that make up the "body" of the fungus, and these look like cotton wool threads. They can, in some instances, be quite long, over 1 cm. So that's another thing to think about. Both Finrot and Fungus are latent in all aquaria, even well maintained ones, since the bacteria and fungi responsible normally do good work breaking down waste materials.
Consequently they have the potential to come out of nowhere when conditions turn bad in the aquarium. Anchor Worm, and indeed most of the other large external parasites, have complex life cycles that cannot be completed in aquaria. They only really become problems in ponds, and because Goldfish are farmed in ponds, it's newly imported fish that are likely to carry them. Once exterminated, Anchor Worms rarely turn up in aquaria ever again.>
I've done some reading about Anchorworms and I've decided to quarantine him, because he doesn't seem to have any other wounds where the worms could've reproduced. Should I keep him in quarantine and treat him, or should I treat the main tank?
<Quarantine, treat and observe the fish until you are happy he is no longer infected. Free living parasites could potentially hitchhike from the quarantine tank to the display tank via buckets, nets, etc. so take care to
isolate the two tanks as fully as possible. Disinfect buckets, nets, etc. using a strong brine solution (50 g/litre cooking salt should do the trick). Anchor Worms are normally treated using organophosphate insecticides to kill the free living stages, with the adults ideally removed by hand. This is fairly tricky to do, but worthwhile if the insecticide isn't killing the adults quickly. Place the goldfish in a waterlogged towel, wrap the fish securely to hold it firmly, and then pull away the adult Anchor Worm using forceps from its head, NOT it's tail (it's a lot like removing ticks from dogs, if you've ever done that). Dab the wound with some sort of antiseptic such as mercurochrome, iodine, tea-tree oil, etc. It would be a very good idea to use something like tea-tree oil proactively in the aquarium once you're finished to prevent secondary infection, though if only the tail fins are affected, the risk of trouble is very small. You may decide to dip the Goldfish in seawater for a few minutes prior to manual removal of the parasites; although this won't cause serious harm to the Goldfish, and doesn't kill the parasite, it does weaken the parasite, making it easier to remove them. Make up seawater using 35 g per litre non-iodised cooking salt or aquarium salt; don't use regular
marine aquarium mix because that raises the pH and hardness, which won't be appreciated by the Goldfish. Dip the fish using a net, and leave for several minutes, potentially 15 minutes, but remove the fish at once if it
shows signs of distress such as rolling over. You can now pull of the Anchor Worms a bit more easily than otherwise. After a couple of weeks, if there's no sign of any more parasites on the fish, and you've finished the treatment of insecticide, you can then move the Goldfish into the display tank.>
I know this isn't fin rot, there is nothing else wrong with his fins or with him, he's eating and swimming....
Thanks for your time!

Anchor worm and platy fry 12/30/08 Good evening, <Hi,> I'm new to the hobby and about a month ago I introduced a female wagtail platy into my cycled tank. Little did I know, I soon had a brood of fry :) Wanting to ensure the safety of the fry and it being a well planted tank, I moved the mother to another tank. <Floating plants the way to go with these livebearers; instinctively the fry seek shelter in the leaves/roots of floating plants, and it's easy to see them there and scoop them out. The fine roots of species such as Limnobium trap algae and organic detritus, providing lots of good "grazing" for Platies, both newborn and adult.> A few days later, in the fry tank, I noticed small crustaceans which I first thought we daphnia--either way the fry were happily eating them! After a lot of reading on my new hobby, I spotted a male adult anchor worm in the tank today. Needless to say, I removed the little b*****! <Are you sure it's an Anchor Worm? Actually NOT AT ALL common in aquaria, and while can be introduced on live food collected from a garden pond, unlikely to come from farmed Daphnia bought in a reputable pet store. Because Anchor Worms need intermediate hosts to complete their life cycle, they die off eventually in aquaria, rarely reaching population sizes large enough to do any serious harm.> I've seen spotted a couple of adult female anchor worms in there and they have gotten the same treatment.. My question is with the platy fry being about two weeks old and only about 4 millimeters (excluding tail) can the anchor worms do any damage or should I treat the tank or move the fry to another tank? <In theory at least, Anchor Worms can harm any fish, in part as parasites themselves, but more seriously by creating wounds that can become infected. But I honestly don't believe this is the issue here. Portions of live food from the pet store may contain other crustaceans alongside Daphnia, some of which might be mistaken for Anchor Worms. They're difficult to treat without recourse to insecticides such as metriphonate, but in an aquarium, the cycle is broken anyway, so there shouldn't be a long term problem.> Thanks for a great web site and, of course, any help, Sam <Cheers, Neale.>

Goldfish Parasite 11/07/08 Hello crew. Recently I looked at my goldfish and noticed sort of a white thing sticking out of his skin. It looks sort of like a pimple. I researched, but I could not find a picture that looked like the parasite on my fish. Can it be some type of anchor worm? Are there many different species, because this parasite does not look exactly like the pictures online. For example, it does not have a forked tail. What should I do? Pull it off? In the meantime, I dosed the tank with a 0.3% concentration of salt. Hopefully it will kill the parasite. Thanks. <Greetings. Anchor worms are very distinctive, and obviously look like small black anchors stuck to the body of the fish. They're pretty uncommon in aquaria, and are more of a pond thing. Anyway, fish can get "pimples" for all kinds of reasons. Goldfish have spawning tubercles on the face when sexually mature, and many aquarists mistake these for parasites. Small wounds cause by rough objects in the tank or careless handling can develop into little blisters. These usually go away by themselves, but treating for Finrot/Fungus proactively isn't a bad idea. Whitespot and Velvet both form white cysts on the skin. Dead skin looks like white fragments; Finrot looks similar but with red inflammation, while Fungus looks like white cotton threads. There are also things called Fish Lice (Argulus) that may be observed as round, off-white parasites on the skin. These are also a pond rather than aquarium problem most of the time. In other words, without a better description or a sharp photograph, we can't diagnose the problem. I've listed the more probable explanations here: now spend some time researching each of them to diagnose the problem yourself. Cheers, Neale.>

Anchor worms on Rainbowfish, reading 8/9/08 Hello WWM Crew! You are the best! After finally getting our 20 gallon tank established and balanced - got rid of Planaria problem after being educated about overfeeding habit - we decided it was safe to introduce 2 Turquoise Rainbowfish to our community - 3 Emperor Tetras, 3 Scissortail Rasboras, 1 Swordtail and 2 Mystery Snails that I would like to get rid of, but my daughter loves them - and no one in Orlando sells Nerites. We also have 1 surviving Gourami hatchling (3 wks old and a little bigger than 1 cm > now) in a breeder net being fed baby brine shrimp that we hatch ourselves. (Parents are off to a new home after spawning). Thought I was safe getting the Rainbows from my local reputable LFS, so sadly did not quarantine - and lo and behold - Rainbow 1 has a big fat anchor worm (almost 1 cm long) just below his dorsal fin near his tail, also has a little wispy white fuzz on his mouth. Rainbow 2 has slight fuzzy mouth as well. I checked your site and others pretty thoroughly and am confident this is really an anchor worm. Not sure what's on the mouth though. Picked up Clout today - have no hospital tank, so treated entire tank with Clout this evening <Need to remove the adult Anchorworm (with tweezers) and the snails> - per instructions - and will pray for the best. Question, after treatment is complete - and IF I am successful in getting rid of the parasite(s), would you recommend a complete teardown of the tank to clean the substrate as well? <Mmm, no> Or is the Clout treatment sufficient? <Can be> I would hate to have a reinfection. <Actually, reinfestation> The tank is well planted and I read on WWM, that I can dip the plants in alum and water. Do I rinse in clean de-chlorinated water again before re- planting, or just straight from alum dip back into tank. <I would not dip/bath the plants in alum...> Also - would a complete teardown require re-cycling the tank before re-introducing <Depending on how thoroughly the tank, contents were sterilized. Again, I would not take the tank down...> the fish, or is the filter biomedia safe once treated with the Clout in the system? <Safe? "It" is largely unaffected by the ingredients> Just learned you have written 2 books on marine aquaria - will you writing one for freshwater enthusiasts as well? <Mmm, have done... parts/most all of which is "in articles" that are WWM in part...> Thanks again in advance for your help that is always spot on! Sandy <Please do read (again?) here: http://wetwebmedia.com/FWSubWebIndex/anchorwrmfaqs.htm Again, adult Lernaeids must be physically removed... the organophosphate will NOT treat/kill them on the fish... the Mystery Snails must be removed during treatment... Bob Fenner>

More help needed please Re: Anchor worms on Rainbowfish 8/9/08 Today: Rainbow 1 - the main part of the Anchor Worm has fallen off, but small trails remain. <So?> Rainbow 2 developed a smaller anchor worm extension, which is now gone. Mild fluff remains on both mouths - is this Ich, or something to do with the Anchor Worms? Is it treatable with Clout as well? <... not likely> Since the anchor worm is still partially in the fish - I will attempt to remove and apply mercurochrome as well - <Ahh!> should I administer a second dose and if so, how much longer can I safely use the CLOUT to ensure eradication? <Is posted on the package...> If so, I plan to do partial 25-30% water change and then add second dose according to package instructions. <Good> After much reading, I have learned that there are probably anchor worm eggs throughout my tank now and that Clout will not kill the eggs. <Correct> How do I get rid of this problem for good? <Keep reading> I saw your link about DTHP, but that was for use in a pond. How can I use it in a small 20 gallon aquarium safely? <Mmm... you are using it... more reading> ALSO NOW - I noticed one mystery snail slowing down today. <... what is going on? Oh... not enough reading> I removed both after reading your reply. <Ah, good> Thanks. I put them in a bag to acclimate them to the other tank when I noticed what I think are small black parasites on the fleshy part of one snail and some in the water in the bag - about a dozen. They are smooth, narrow and elongated about 2-3mm long each and less than 1 mm wide. I noticed some at the top of the gravel as well. What can this be and what do I need to do about it? >Nada...< So now they are in a bucket with clean tank water from another tank until further notice. I specifically asked my "expert" at the LFS if Clout was safe for the snails, - he said yes. I will have to find a new LFS. <Blame the act not the child> Besides the Rainbowfish, all others are healthy - so far - but I assume I have to treat as if they have also been infected/infested - correct? <You've treated the system...> Would it be wise to add Aquarium salt as a therapeutic measure for the rainbowfish right now? <No wisdom; no> What about the water temp? Would it help to elevate the temp or not? Temp is usually in the 78-79 degree F range. <Ditto> Off to get mercurochrome and wait for your reply. Thanks again ever so much. Sandy <Bob>

Final update with question Re: More help needed please Re: Anchor worms on Rainbowfish 8/10/08 I did TRY to get any remaining parts of the anchor worm out, but it was too limp to grasp even with tweezers. I ended up grabbing a scale and thought it best to stop there. It seems a bit more firm today, so I will try one more time. <Mmm, likely no to not enough need/use in such trying... if dead, the adult will simply dissolve...> After reading some more and watching the snails in the bucket, I think what I saw was actually just copious snail waste - I hope so. <Likely so> Both Rainbows seem to be on the mend. They seem to be swimming less erratically now, and the others seem no worse for wear. Will stop the treatment today and insert new carbon into filter. Will do several water changes every few days over the next few weeks. I read that because of the anchor worm life cycle, I need to watch closely over the next few weeks to see if they come back - and that they probably will - and then will have to treat with Clout again. <Yes> I also came across this: http://www.zamzows.com/Default.aspx?tabid=1688&newsType=ArticleView&articleId=659 I assume Clout does not contain Dimilin, or else it would state that it would also interrupt the life cycle. <...

Salt- Koi- Goldfish... and Anchorworm evidently 8/5/08 Dear WetWeb Crew, Could someone there tell me the correct amount of salt to use for medicinal purposes-salt bathes. My Koi and Gold fish have a parasite on them. It looks like a barb or needle sticking out of the base of the dorsal fin. Also how long should I leave them in the salt solution. I would greatly appreciate your help. Thanks for your time. John. <The following is a table modified from "The Interpet Manual of Fish Health", a useful little book: --- 0.1% (1 gramme per litre): General additive for livebearers or in tanks where fish show physical damage (i.e., lesions, fin damage). Use in the aquarium. 0.3% (3 g/l): Reduces nitrite toxicity or to treat physical damage. Use in the aquarium. 0.3-0.5% (3-5 g/l): To control Hydra. Use in the aquarium for no more than 5 to 7 days, then change water to gradually reduce salinity. 1% (10 g/l): To treat ulcer disease on coldwater fish. Acclimate fish gradually and then reduce salinity gradually once fish are cured. 2-3% (20-30 g/l): To remove leeches from pond fish. Use as a bath, with fish put into bath for 15-30 minute dips. --- In you case, it sounds like you have leeches or anchor worm. Salt dips will certainly deal with leeches, but anchor worms will need a specific treatment of some sort. Salt won't help because the free-living stages are in the water column, so even if the adults are killed, another generation of anchor worms will find their way onto your fish. See here: http://www.wetwebmedia.com/PondSubWebIndex/contrpdparasit.htm Your local pond supplier may well have a variety of other treatments available. Cheers, Neale.>

sick orander - stick like threads sticking out of bodies... Mis-stocked, uncycled Goldfish system of too small size, Anchorworms 4/19/08 Hi, Firstly apologies if there is info on your site about this. I have scoured Google and your site for many hours and finding nothing that sounded like this, I finally decided I need to ask for direct help! About 4 and a half weeks ago we bought a 15 gallon cold water tank, under gravel filter, pump, gravel, and live plants as a present for our 4 year old son to start having his first pet. Before buying it we went to the pet store and asked advice about what we could have in it, how long we needed to run the tank before introducing the fish, which ones could go together etc etc. They recommended two small Oranders <Orandas, fancy goldfish... will need more room than this...> and said the tank needed to run for at least 48 hours before introducing the fish. <Uhh, no... more time... to cycle... read here: http://wetwebmedia.com/FWSubWebIndex/gldfshsystems.htm> We let it run for 72 hours, floated the bag with the fish for 20 minutes and so our journey began. 'Goldie' and 'Parp' (he's a four year old boy - what do you expect him to call them?!) appeared happy at first but on day three we became concerned about Goldie 'she' was listless and hanging at the top of the water but not gasping. The shop suggested she may be stressed by the change and recommended a tonic containing Bronopol, Copper EDTA, Formaldehyde and silver Proteinate. <... a very poor idea> By the next day she was much happier as were we. Two days later (5 days after fish introduced) we noticed Goldie's tail and 1 or her fins were ragged and disappearing, we then saw Parp nipping at her. We researched on line and many sites said this can happen with a new tank and it should settle down. <Mmm, no. Most often fish's die from such treatment> She also appeared to have a white thin thread coming from her side. We spoke to the store the next day who said it may have been that she had fin rot and parp was trying to make her better and to try Phenoxyethanol. <...> She improved greatly, the thread dropped off and all was well until the water began to cloud (about day 6). We did 10% water change we had been told to do, using a gravel vac and the next morning the water was very cloudy. <... ammonia, nitrite?> My husband went to the store and they recommended bringing in a sample the next day. By the time we got home the store was closed, we could hardly see the fish and they were gasping at the top of the water. Again we turned to the internet and were recommended a 50^% water change with the suggestion it was bacterial bloom. The fish settled down, although the water didn't. <Cycling...> Back at the store the next day they tested the water and the test went bright purple - they said we needed to bring down the PH. They said the problem may have been from using two treatments with less than a 7 day gap (as the last store had advised us to do!) They said not to change anything that day as we had changed so much water already, and do a 20% change the next day, then two days later take back another sample. After the 20% change, the water really cleared and all appeared to be improving - until!!! - the stick/thread like things appeared again, this time out of both of the fish. <Anchorworms... Lernaea... Read here: http://wetwebmedia.com/FWSubWebIndex/anchorwrmfaqs.htm> The shop said the water level was much improved, ammonia was up a bit but not vastly (they didn't give me numbers) <Any amount present is toxic> and another water change two days later and reduced feeding should sort that. <Ah, no> They also tried to contact their suppliers to see if they had any idea what the attachments could be. <Ditch this store> We reduced feeding to once every two days on advice but now one is hanging at the top, one sitting on the bottom, or occasionally hanging almost vertically mid tank and we don't know what else to do or where else to go for help. I have tried desperately to get pictures, but am obviously not meant to be an animal photographer. The attachments are about 1 cm long and then at the end are split in two. The are essentially white, although one or two have become a little darker tonight. <Good description... these are crustacean parasites...> They don't appear to move at all but are just like little sticks. Parp has one at the base of 'his' tale but that has now developed a white fluffy area at the bottom of it. PLEASE can you help? I just don't know how to help them. Thanks for your time Erica (and more importantly Goldie and Parp) <Please read where you were referred to above and here: http://wetwebmedia.com/FWSubWebIndex/fwestcycling.htm and the linked files above. You have made a few simple though drastic errors... as you will soon realize... the means to possibly fix them will be detailed in the reading. Bob Fenner>

Re: sick orander - stick like threads sticking out of bodies 4/22/08 thank you for your help. Your advice was really useful - feel like we have been trying to be really responsible and get advice, but now find it was bad advice - unfortunately it is the fish that suffer. <Yes> Sadly Goldie died yesterday, but she had become very ill. Parp seems to be beginning to recover, so we are crossing our fingers we can get through this bit to get him steady and once again a happy fish. Still concerned over the cloudy water, but following the advice from the links you sent and crossing our fingers. Thanks again Erica <Welcome. BobF>

Goldfish developing lumps in fin and red sores on body - Urgent help needed! -04/11/08 Hi, Thanks for maintaining this wonderful site, it really has tons of useful info. <Welcome and sorry for the delay in reply here...> My two new goldfish have a problem and I am unable to diagnose even after going through the diseases FAQs, could you please help? <Yes... have looked at your pix and have a good/high confidence re the root cause and cure here> My tank is 90 gallons and there are 5 fish in it - 2 Orandas (Lionheads I think) which are about 4 inches long (body only), 2 baby Ranchus (2 inches long) and 1 Pleco (5 inches long and I will soon remove it). <Mmm, I keep Hypostomus... one of the "medium size species" Plecos with my fancy goldfish... not usually a problem in this size/sort of system> The water is (and has been) clean - 0 NH3, 0 Nitrites, 10ppm Nitrates, pH is 8.2 though (my tap water tested 8.0). Water is aerated constantly and has a filter which pumps water overhead and back through sponges. Some background - I got the 2 Orandas eight days back and they have been fine so far, eating well and not constipated. One of them (store said it is a she) is a bit plump and spends a lot of time just floating near the filter in a dark corner. Sometimes, she floats a bit lopsided (leaning to one side). On one side, her tail fin seems a bit bent and this makes her swim with a clumsy, wriggly movement (the tail fins don't open up fully at all). I am not sure if she has some swim bladder problem or if the tail fin hurts when she tries to swim but she does seem happy otherwise. The 2 Ranchus were brought in 2 days back and are so far eating and swimming actively with no visible signs of disease. Today, both of them have developed what seem like whitish lumps inside their tail fins (mostly near the base). <I see these> Also, one of them (not the floater) has developed three or four red sores on its body (it looks like a scale has been peeled off here and there exposing the blood behind). There is no worm sticking out of the sore, <There will be...> no mucus, no yellow, just red like it was poked with something sharp. The two little Ranchus seem to now be chasing them to try and get at the blood and the lumps (the Orandas don't seem to be harassed too much by this though). I have attached some photos which show the lump and the sore (marked in white). I can sense that they are going to get worse tomorrow so could you kindly let me know what it could be and how to treat it? I am planning to move them to quarantine now after giving them a 10 min treatment in a 10mg/Litre solution of Potassium Permanganate with an aerator in a bucket. <Mmm, it's obvious you've been studying... I would not use the KMnO3... too harsh and won't solve the issue here> Thanks again in advance, Shankar <And now (finally!) my input. This is very likely the beginning of "Anchor Worm"... a crustacean parasite complaint... at times common with pond-reared goldfish... Needs really to be treated with an organophosphate... usually Dimilin or DTHP/Masoten/Dylox/Neguvon... and other generic names... Please insert the term "Anchorworm" in your search tool, or the one on WWM. Cheers, Bob Fenner>

Re: Goldfish developing lumps in fin and red sores on body - Urgent help needed! 04/14/2008 Dear Bob, Thanks very much for your reply. You are right, it is indeed turning out to be Anchorworms. <Ahh! and ouch!!!> I have tried and removed them whenever I see them dangling out more than 2 mm and have been mostly successful (except a couple of cases where I couldn't get the whole worm out). Dabbing the worm with a swab of cotton soaked in potassium permanganate seemed to help while pulling them out but I cant say for sure. The whole thing seems to be subsiding but, to make sure, I started treating the tank with Paracidol (copper sulfate based medicine). <I would not do this... too toxic and not likely to kill the free-living forms> The bottle says 3 doses alternate days and that it will remove ich also, hopefully I should have a clear tank in a week. <Again... the use of an organophosphate> Another thing - the guy at the pet shop told me it is a 360 litre (~ 90 gallon) tank but when I actually measured the dimensions of the water column (minus some allowance for rocks), it looks like I only have 65g! <Very common to have such a difference in real volume> So I guess I will have to restrict to just 4 or 5 goldfish:-( <Good point, call> Thanks again for the wonderful site, I now read it everyday because it is so informative (and entertaining). -Shankar <Thank you my friend. Bob Fenner>

Spots on my Kissing Gourami, likely lernaeids -12/14/07 Hello, <Stephanie> I have had a kissing Gourami for a couple of years now but over the last few days it has developed about some spots which I put down to a bacterial infection <Mmmm> and so I've been treating with a fungus, Finrot and bacteria treatment. But the spots, which appear to be only on one side of it's body have turned a peachy/orange colour and each seems to have something like a black barb type thing sticking out of it - almost like a splinter. <Ahh!> There are approximately 5 of these spots and they are in different places on the body and one near the eye. The fish seems to be well enough at the moment it is eating and behaving as usual. Do you have any idea what this might be? <I do... most likely a lernaeid, aka Anchorworm... Please see here re: http://wetwebmedia.com/FWSubWebIndex/fwcrustdisfaqs.htm and the linked files above. Had you recently added "something live" (new fish, FW food, plants) to this system? The parasite had to have been added some how... See Google Images for the common name as well... Cheers, Bob Fenner> Many thanks, Stephanie

Re: Spots on my Kissing Gourami -12/14/07 Bob, <Steph> Thanks so much for your response. Thanks for the link and "yuk" it looks like Anchorworm! I bought some new plants about a week ago. So, up go my sleeves! <Ahh!> I've pulled the things off with tweezers and now breathe a sigh of relief - so does my Gourami! <I'll say!> I've bought a bottle of parasiticide which I'll have to administer tomorrow as I have been treating the fish for a bacterial infection and it says to wait 48 hours before using. <Good> Thanks so much for you swift response and the link - much appreciated! Stephanie <Welcome my friend. BobF>

Newbie /anchor worms and Camallanus worms, FW 12/12/07 Dear Crew, First let me apologize in advance for any posting errors. I have never posted anything before. I have read just about everything I could find on your site and the web, and still haven't found a clear answer to my question. <Welcome> My eight year old son and I are relative newbies to freshwater aquariums, but we are learning fast. Several months ago, we got a 5 gallon aquarium, with one live dwarf Amazon sword plant. We have a small under gravel filter from our previous 2 gallon tank, a small heater and a corner box filter, air pump (suitable for up to 10 gallon tanks). There is a tiny snail, which I have only seen once. I assume it came with the plant, and I don't know if it is still alive. After a couple of weeks we got 1 fancy guppy. We had him about three weeks, and then got another guppy and an Otocinclus. We did not quarantine (a lesson which I have since learned), I also learned about water testing around this time. Within a couple of days, the new guppy died of fin and tail rot, and the Oto had ich. I treated the tank with MelaFix and malachite green. <Better to simply elevate temperature here.> The Oto struggled with ich off and on for several weeks, and eventually died. Throughout all this, the original guppy appeared healthy. As I learned about water testing during this time, we have been at ammonia 0, nitrites 0, nitrates 2.5-5, ph 7.6-8.0. now for several weeks. We waited several more weeks, before attempting to get any more fish, and on 11/24/07 decided to get 2 more Otos to help with the algae. <Mmm, I would not place Otocinclus in such a small volume, with such a high pH... better to seek out other means of algae control. Posted on WWM> They are currently quarantined, and so far appear healthy. The day we brought home the new Otos, I discovered a parasite hanging off the side off the guppy. After investigating on line, I am sure it was an anchor worm. I removed the box filter/charcoal and I started to treat with Jungle Parasite Clear, which said it was good for anchor worms <... but adults, on host fish/es... must need be physically removed...> and would not harm the plant like Coppersafe. The anchor worm fell off, leaving a gaping wound in the side of the guppy. Despite this, he continued to eat and was active. A few days later, several red worms protruded from his anus, and one from the gaping hole in his side. After more searching on line, I am sure from the photos I have seen on line that he had Camallanus worms. <Mmm... no... these Nematodes are stark white, round in cross section... Likely what you are seeing are other/new Anchorworms...> I continued to treat with the Jungle Parasite Clear which contains Praziquantel, Diflubenzuron, Metronidazole, and Acriflavine. <Mmm... none of these will treat for, kill Lernaeids... Please read here: http://www.wetwebmedia.com/FWSubWebIndex/fwcrustdisfaqs.htm and the linked FAQs file above on Organophosphate Use> This appeared to have no effect on the worms, and the fish has now finally died (whether from the worms or the wound). So my basic questions are these? <Likely crustacean... Anchorworms> What do I treat the tank with to ensure anchor worms (which I know is not a worm) and Camallanus worms (theoretically they have a 30 day life cycle) are gone (since the Jungle Parasite Clear didn't appear to treat the worms)? <Not worms... just appear worm-like> What is safe for the plant? <Please read the above...> Is the snail an intermediary host? <Mmm, no> How long do I need to wait, keeping in mind I have 2 Otos in quarantine, waiting for all the algae in the tank. Do I need to take down the whole set up and sterilize and start over? <Mmm, possibly the best approach here now> If so, how? <See here: http://www.wetwebmedia.com/clnaqfaqs.htm> How do I keep the bacteria going in the tank since there are now no fish in there? <They will be there> Thank you in advance for your advice. I have learned much from your site. I wanted to introduce my son to the pleasures of an aquarium, and all he has seen so far is a bunch of parasites and sick fish. I realize we have just a tiny set up, but I had an aquarium when I was growing up, and I wanted him to have the same pleasure it gave me. I'd just like to get the new Otos settled. We know the 1 inch per gallon of water rule, so we know we can only have a few small fish, but we want them to be healthy, happy fish. Thanks again for your help. Vida <Thank you for writing so well... Clearly and completely. I want to state, make it known to you that the difficulties you and your animals are suffering are not of your origination... The livestock you have received has been infested, compromised... and not easily cured by anyone's efforts. I would either bleach-wash and start over here, moving the water from the Quarantine along with the Otocinclus... and feed carefully till the system is established. Otherwise, Clout (tm), Fluke Tabs (tm), other DTHP or Dimilin containing pesticide can be added... Do please write back if you have further concerns, issues. Bob Fenner>

Re: newbie /anchor worms and Camallanus worms 12/18/07 Mr. Fenner, <Vida> Thank you for your prompt reply. I think I will take every thing down and bleach it out. Is there any way to save the plant? <Yes... can be peremptorily dipped/bathed in an alum and water solution... See WWM, the Net re> We like having a live plant as opposed to plastic. Likewise, how does one safely add new live plants, as I realize they can introduce parasites? <Rare, but yes... most all that is wet can/may> If we are starting all over, we will probably add another plant or two, and definitely don't want to introduce any new parasites. The Otos in quarantine appear healthy and thriving, and my son would like them in the tank. Here are some photo links, which show the photos why I believe the fish had Camallanus. This looked very different from the anchor worm on its side, and definitely appeared to be multiple red worms in the anus. They would pull in and appear much shorter at some times than at others. The anchor worm did not do this, it was the same until it fell off and left the wound on the side of the fish. My husband, who has a background in biology and a PhD in genetics, also felt that the organisms protruding from the anus were Camallanus and not the same as the anchor worm. http://www.inkmkr.com/Fish/CamallanusTreatment/experience.html http://img520.imageshack.us/img520/2897/parasiteen0.jpg http://www.gaem.it/pubblico/articoli/malattiepesci/Camallanus/camallanus03.jpg <I must commend you on your photographs. Some are very nice indeed... These do appear to be Nematodes... reddish from feeding likely> I had tried elevating the temperature of the tank to between 85-90 degrees (normally it is at 76 degrees) and adding a small amount of aquarium salt for the ich, but was conservative with this because of the plant and the oto. The pH of the aquarium was running 7.2-7.6 before treating with the Jungle Parasite Clear. I suspect some component of the medication fizzy tab has increased the pH. <Possibly...> Thank you again for your assistance. Vida <Thank you for this follow-up. Bob Fenner>

Goldfish lice -- 08/02/07 Hi how are you. <Tolerably well, thank you.> I had emailed earlier for the goldfish lice. <Yep.> It had happened to all my 9 fishes. But then I removed it with my hand and then all of them became fine except 2 which died. <OK.> Now after 3 months I again discovered 2 lice on my 2 fish. However I have removed it and now none are seen in the tank. But pls tell me that what more precaution can I take. Any medication. Or what. <Try and understand how the lice get into the tank, for example, by buying fishes from retailers with a goldfish lice problem.> Also pls tell me that why these lice happen. Any reason behind it. <Reason? Evolution. Parasites have evolved to take advantage of host organisms. But why they occur in your tank? Simple: you aren't quarantining your fish. If your fish are isolated from infected fishes, they won't get the parasites. If you dump infected fish from the shop into your aquarium, your fish will get infected.> I had bought 3 fishes a week before and added in the tank. Is it because of them because among the 2 which got infected one was the new one. <Likely, yes, assuming you killed off the lice last time round.> Pls tell me the reason behind it and what precaution should I take <The usual precautions will work: buy healthy fish from trustworthy retailers. Quarantine new stock, treating for parasites if you suspect they are infected. Hope this helps, Neale>

Re: Goldfish lice -- 08/02/07 Thank you for your efforts and advice. Pls tell me that how can I quarantine the new stock. Any medicines. Also the fish vendor from whom I purchased the fishes say that the fishes are always under the medication in his shop. Pls tell me any medicines or antibiotics so that I can cure them. Also after finding 2 lice what more precaution can I take so that other fishes don't get infected. Pls help <Hello Mr Bond. Quarantining is described in most aquarium books, and is simple enough to understand: keep new fish in a *separate* aquarium for a few weeks, long enough for you to observe their health. Six weeks should do the trick. In that time, you should see evidence of fish lice, whitespot, or whatever and be able to treat it safely. After quarantining is over, you move the fish into your display aquarium. All fish retailers will say they quarantine their stock. Can you imagine them admitting otherwise? To be fair, most actually do quarantine their stock to some extent. But the problem is that display tanks in the store mix lots of fish together -- they have to, since the retailer can't place one goldfish per aquarium! So, simply by being placed on display, the fish are exposed to diseases. Medications for treating fish lice depend on what's available in your area. In the UK, it's products such as Interpet #12 Anti Crustacean Parasite and Waterlife Sterazin. In the US, you have things like Mardel CopperSafe and Aquarium Products Fluke-Tabs. Visit your retailer, and see what they have available. Saltwater dips might also work. In this case, add 20-30 grammes of salt per litre of aquarium water in a bucket. Net the fish, and immerse in the bath for 5-20 minutes depending on the size of the fish (bigger fish tolerate dips for longer). Repeat daily, and with luck the lice will drop off. I'm not a vet, so can't comment on antibiotics, but since antibiotics are for bacteria, there's no reason they would work on lice. Hope this helps, Neale> Re: Goldfish lice -- 08/02/07 What are the medications available in India for fish lice. Here all stupid people sell fishes and so they don't know anything. Pls recommend it. Is there any particular reason why these fish lice happen <Mr. Bond, some manners please. How about saying "please" or "thank you"? Over here in England we still take these things seriously. Anyway, as for brands of fish lice medication in India, I haven't a clue. The following medications are used in the US, UK, and Europe to treat fish lice, and some may be available in India. For all I know, there may be Indian pharmaceutical companies producing their own brands. A bit of time spent visiting aquarium stores or shopping online may help. - API General Cure - Aquarium Products Clout - Aquarium Products Fluke-Tabs - Aquarium Products Life Bearer - Hikari CyroPro - Mardel CopperSafe - Seachem Cupramine - Seachem PolyGuard - Interpet #12 Anti Crustacean Parasite - Kusuri Parazoryne - Waterlife Sterazin - JBL Gyrodactol - TetraMedica ContraSpot You probably want to see if there's an Indian or local fishkeeping club you can join. That's often the best way to make friends among fishkeepers near home, and so learn about the best places to go shopping and what products and traded. As for "why" parasites happen, I think I explained that before. When a healthy fish and a parasitised fish are brought together in one tank, then there's a good chance the parasite will infect the healthy fish. Your job is to prevent that happening. Bob's written a nice intro to the subject, here: http://www.wetwebmedia.com/quaranti.htm . Hope this helps, Neale>

Anchorworm, using WWM 7/7/05 Hi, Thank you for creating such an informative website. I learned so much from it. :) I just plucked an anchor worm off the tail of my goldfish. I could not find information of what to do with the goldfish - should I quarantine it or release it back into the container pond? At the moment now, it is in a 1 gallon tank. I don't have space in the townhouse to set up a real QT tank. All the other fishes seem healthy. Thanks, Lai Hwa <... go to the homepage of WWM: http://www.wetwebmedia.com/index.html put in the term "anchor worm" in the Google search tool... Bob Fenner>

Anchor worm on a molly? We have a gold dust molly we purchased her with a mate about 6 months ago her mate died about 1 month ago and now she seems to be get fat quite fat under her belly she has a white round opening and it seems to have a well I am not sure what it is it looks like 2 red thin things sticking out it sort of looks like one have of a sword tail maybe I am really not schooled in fish and the fish belong to my 9 year old daughter she wanted fish so my husband them for her we have a 30 gallon tank with 6 fish neons, the molly, and zebras, and a head light tail light with 2 of the cleaning fish one is large and one is small I am worried about the molly my husband says fish lay eggs but from my research I see that is not correct please help clueless <Does sound like anchor worm, Lernaea (actually a copepod).... please put this name, term in your search engine, look at pix... and if this is so, consider carefully pulling these adults off the fish (with tweezers)... W/o intermediate hosts (snails) they cannot (likely) reproduce in your system. Bob Fenner> Parasite in Parrot Gills Hello I have lost two parrot fish in the last three months. They all have long red tubular growths coming from the inside of the gills. The gill area has busted open since they got this and is growing out of the gills. The aquarium store told me it was most likely gill flukes and so I treated them repeatedly with no cure. They told me that they were a hybrid fish and if they appeared to be OK them let them go. I did and I lost one parrot 3 months ago and 1 last night. I noticed last week that the red tubular growths had purple tips on them and that the rosy barb in the tank was sticking its head into their gills and eating it. Please help. I've had these fish for over three years and I am very attached. The aquarium seems to think they may be anchor worms. There are two angel fish, a Pleco and a rosy barb in the tank and they do not have these growths. Kathleen < To get rid of either gill flukes or anchor worm I would recommend Fluke-Tabs. If your local store does not carry them then you can order them online at DrsFosterSmith.com.-Chuck>

Anchor Worms Hi, I have a 90x37x32 tank with various livebearers in. By the way I have 10 tanks of various sizes. I recently purchased a couple of platies and 4 Siamese fighter females and 1 male with about 4 new plants. (Not from a reputable dealer!! - mistake no 1). The tank has been running for about 4 months now. In the past 3 weeks my male Siamese fighter and 3 females had anchor worms (worm with a v tail) which I have treated successfully with Interpet No13. I treat the fish in a hospital tank. I purchased 4 more females of which two acquired the worm again. They are undergoing treatment. <I suspect this is the economic poison Dimilin... or the older DTHP (Masoten, Dylox...) Please see here: http://www.wetwebmedia.com/PondSubWebIndex/contrpdparasit.htm> My question is how do I cure the tank without damaging the plants which by the way are stunning. I do realize that I will have to strip the tank which is no problem. My plants are my concern. <The plants should be fine if the product mentioned is either of these organophosphates. If it is something else, please write back, Bob Fenner> I trust to hear from you soon. Kind Regards, GRAHAM LIGHT SOUTH AFRICA
