co-factors...There are many free-living, and commensal life
forms also that go misidentified as parasite fauna...Otherwise, skin scrapings, possibly sacrificing

I can’t help but notice when certain fish swim to my not powerful LED
light up top (current marine, fish only type light) that these
certain fish appear to have a white glitter in them. It’s only
when they are under the light , at certain depths and angles.
The fish that show it are a masked swallowtail angel, an asfur angel and
a blue ring angel.
Too numerous to count ( I feel it’s not ich) but almost like a paint
overspray. Description resembles velvet, but nothing is dead and I’ve
noticed this the past 4 days or so.
Again, 3 out of the 25 fish show it, no ones not eating, no lethargy, no
swimming until power heads etc.
Could this just be the way the light is radiating off of them? Have you
noticed this under leds?

Gramma with internal parasites
<Oh! It did download... in a few min.s!>
Howdy, hope you can help me figure out what to try to help save my Royal Gramma.
I suspect an internal parasite, seemingly Protozoans. Attaching a microscope
shot of the ubiquitous pear-shaped creatures that show up in a stool sample.
There are also some smaller paramecium-looking organisms.
<I see the former>
The fish is in QT. I’ve been feeding Mysis and flake food mixed with Seachem
Focus and API General Cure for about three days, with no improvement. I also
treated the water with General Cure since the fish is not eating well (but is
eating *some*), although understand that’s not the best route of administration.
The fish is hanging in. Deteriorating surprisingly slowly, but on its side and
Thanks for any help you can give!
<This does look "Hexamita" like to me. Most folks administer Metronidazole; best
via foods/feeding as you mention. DO search, read on WWM re both the causative
agent and medication. Bob Fenner>
Re: Gramma with internal parasites
Got it. Thanks for the help on ID and will follow up after research. Also,
<Thank you. Please do keep us informed. BobF>
Re: Gramma with internal parasites 4/14/19
Bob, hope you are enjoying Mexico! I read up on WWM’s resources on internal
Hexamita, particularly in marine fish, as well as on metronidazole and other
treatments for that malady. (Incidentally, it was your urging of others on WWM
that led me to break out my 8yo daughter’s microscope to look at fish poo—good
family time, honestly).
So I have distilled this, and would appreciate your thoughts on it and whether
anything further can be done.
- Metronidazole in food, since the fish eats a little bit. I’ve discontinued
putting it in the water for that reason.
- Epsom salt. Added 1 tsp/gallon. Will scrutinize any resultant productions by
the fish under the microscope (see family time above).
- Pristine water. I am using a 1 gal container for the QT. Am assuming the small
size is ok since the gramma is lethargic. Put a PVC tee fitting in to give it a
place to hang out. I replace it every day with water from my DT, so it’s what
the fish has always been used to. Aerate and temp control.
<Sounds/reads very good>
- Watching it. A lot. Maybe staring at the fish will cause the Hexamita to die.
I don’t know.
<Mmm; not staring...>
<Thank you Bob/Bob>
Re: Gramma with internal parasites
Bob & Crew:
The Royal Gramma below is hanging on but I’ve tried something new. There was
zero improvement with the protocol for internal parasites below (posited to
be Hexamita), and the fish was looking more lethargic, with slower, weaker
breathing, and seemed to have stopped eating entirely. I had seen
hex-looking stuff moving in fecal microscope imaging, but I imagine there
could be moving things that are either co-morbid or sub-clinical.
<Good review, update>
When I netted the fish to have a look and examine up close, I noticed that
it was developing the beginnings of a whitish-gray appearance, especially in
the darker/magenta anterior half; couldn’t discern one way or other on the
lighter/yellow posterior half. The ease with which it allowed itself to be
netted was also a clue that its condition was worse. Additionally, its head
was darkening somewhat, and the rest of the body was growing lighter.
It also has for some time had some scattered scales that looked lighter in
its head area. Tail fin has started to look slightly ragged, but no fuzz,
specks, or streaks. Based on reading WWM, this made me think external
<May be..... Flukes? Protozoa?>
In addition to the Hexamita treatment, I’ve started using Rid-Ich Plus,
mostly because it’s the formalin-containing med I have on hand (also has
malachite green). Been doing .5ml/gallon every 24 hours, with significant
water changes. Maintaining aeration of course.
The fish seems improved. More active, respiration is less sluggish. It could
also be that the fish is breathing faster because of distress from the
chemical treatment, but it’s also swimming a bit. Not eating, but upon
feeding, the circulating food seems to pique the Gramma’s interest, even if
it doesn’t actually go eat it. It “seems” improved, even if still sick.
(1) would it be worth the trauma to the fish to do a skin scrape and examine
under the microscope?
<Yes I would>
(2) Formalin+MG ok, or should I go straight formalin? Copper? Quinine?
<Either the combo. or Formalin alone... as a dip/bath>
(3) Any other advice or observation of what i might be missing appreciated.
<Thank you for sharing. BobF>
Re: Gramma with internal parasites
Sorry, I should add that the formalin+mg dosage I’m giving works out to
15mg/L formalin and .05mgL MG.
<Real good. Both "harsh", toxic... danger Bob Murken. B>
Re: Gramma with internal parasites
Will do the skin scrape and further reading on flukes and external protozoa.
As ever, thanks.

White barred boxfish with oodinium
We have 2 white barred boxfish that have been fine for the past few
months and last week broke out severely with white spots
(more like icing sugar than anything) all over their bodies.
<I see this in your accompanying pic>
We did freshwater dips which helped someone what but not a lot and moved
them into a separate quarantine tank where we treated them with Formalin
for 24 hours.
<Mmm; very toxic. Better to use this biocide in dips/baths only>
The boxfish live at 67 degrees.
<I'd keep much lower; like the mid-50's F>
Today, although they are better, they are no where near good. This is a
photo of them this morning after formalin.
Am looking for advice on next steps:
Here are my questions:
From the appearance in the photos, does this look like oodinium (or
<Almost assuredly Cryptocaryon... can be easily checked w/ sampling,
microscope exam. IF Velvet they'd be dead>
As you can see the larger one has lost a lot of colour, which started
happening about 3 weeks ago. I believe that may have been the onset of
the outbreak but the cold water suppressed the advancing parasite.
<Yes; all the more reason to lower it still>
Would hyposalinity be effective for treating these cold water fish?
<Can help; rarely effects a cure>
Should we drop the temperature to change the progress of the disease?
We are picking up some Chloroquine Phosphate, but will not have it until
Thursday. How do we make it until then?
<IF you lower temp.; likely so>
Should the dosage of the CP be adjusted because of the water temp?
Would you recommend something else? (No, I have no access to a cold
water cleaner fish, but wondering if a tropical cleaner fish would
acclimate down to 67 degrees)
<Labroides et al. common cleaners; no>
Thanking you in advance,
and will be in your lecture at MACNA in a couple weeks!
<A good. See you then! Bob Fenner>
Re: White barred boxfish with oodinium
Totally appreciate the comments. I am getting biopsy on Friday.
In your experience, are these fish beyond recovery?

Identifying parasite or bacterial infection
<Hi ya Doug>
I am having a pretty rough time identifying the parasite or bacterial infection
that is present in my Fowlr tank. I have a 60 gallon with a Kole Tang, 3
Firefish, a 3 stripe damsel, some hermits and turbo snails, and a skunk cleaner
<Ohh, my usual blanket statement re such diagnoses: Can ONLY be done via
sampling and looking under a microscope; and even then, at times difficult>
The Kole tang and damsel are pretty regularly scratching themselves
against the rocks, <Not necessarily indicative of pathogen involvement... akin
to you and I, sometimes the environment makes us itchy>
and I lost a Klein butterfly yesterday after who was also flashing. The Klein
and Kole were pretty consistently floating near the shrimp to ask for cleaning,
but for some reason he was hesitant but occasionally did abide. The only
physical signs I see, aside from flashing, are present on the Kole which are
really dark circles on his side, one small one near his eye, and on one of his
side fins. The damsel looks as he always has, but is scratching regularly. I
also noticed one of the fire goby's starting to scratch as well.
My pH is at 7.9.
<Ohh, this is low.... too low. The pH scale is base ten logarithmic... like some
others in the physical world... a difference of a whole point is an order of
magnitude in difference (ten times more/less). DO see WWM re
pH.... you REALLY want it to be about 8.2-8.4 and stable.... there are
ways... gone over. Do you need/want help using the search tool, indices?>
My nitrates are a bit high at 30-40ppm.
<This too is trouble, and/or indicates trouble... SEE/READ on WWM re lowering
and keeping NO3 lower than 20 ppm. These water issues COULD BE the only real
problem here w/ your fishes. I.e., no parasites... or they might be factors in
allowing advantage of parasites, infectious agents to the detriment of
their/your fish hosts>
Ammonia and nitrite are both 0. I tried taking a pic of the Kole but he is
shying away from me when I approach the tank.
I was hoping to get some advice on what to do to narrow down the issue, and
whether or not a freshwater dip would be advisable. Thanks for any advice.
<The reading, correction of their world is where I would put all my
efforts. Oh, additionally, I would be supplementing foods to bolster the fishes
health. This is also archived.... on WWM. Bob Fenner>

only within a narrow range of water parameters, conditions... Has just
been proven itself as a cure>

Atlantic blue tang is showing signs. His eyes are cloudy and his
breathing is rapid. I wasn't thinking and I was using the same cleaning
tools for water changes.
<D'oh! Parasites may be easily transmitted about by anything wet>
My problem is I don't have another qt and my 2 tangs are large, about
4-5 inches. So, would I be able to buy a tote from Wal-mart, remove lr
and inverts and start hypo salinity in the dt. I cannot remove all the
sand because I have to much. What will happen to the sand and at what
rate do I lower salinity to and how long do I leave it at that rate.
<Is this a question? I'd be reading on WWM re Tangs, Crypt, Cures that
work... do you need help using the search tool, indices? Bob Fenner>
Any suggestions would be helpful. I have had this tank running for 3
years and have 2 large tangs that I don't want to loose. Thank you.
Re: Ich issue
Sent from my iPad. I am sorry I bothered you about this problem.
I just wanted to know if hypo would kill my sand bed.
<... you've confused what WWM is... you can just look this up.>
I thought it might be less stressful to remove the live rock and inverts
than to cram 10 fish into a smaller tank. I know my mistake was stupid,
and I am sick about it. I was just looking for some help or suggestions.
I won't bother you again. Sorry.
<Not, never a bother; but do put yourself in our "place": We have no
idea what you already "know"... and can't spend the time
re-writing/keying "complete answers" to vague, broad issues... HENCE the
accumulation of input (FAQs) and survey articles covering common

I lost my Atlantic blue tang 4days ago and I don't know if I am dealing
with ich or velvet.
<Only can be ascertained by way of sampling and microscopic examination.
Have you read on WWM?>
My other tang and assorted fish seem to be doing ok other than a few white
spots. I lost the abt during a fresh water dip. I think he was too far gone for
this. If this is velvet would I be seeing symptoms on other fish by now or does
it take time to show up?.
<Takes no time... all would be dead if this Dinoflagellate. READ>
The symptoms my abt had were loss of color, erratic swimming, and heavy
breathing. I never did see spots on him so I was thinking velvet but am not
sure. Other fish are eating fine, breathing normal and are not showing signs of
stress at all.

|Need a parasite
ID/treatment recommendation... ... toxic situation
Hello WetWeb Crew,
I seem to have come across an unknown parasite,
<?... the pix attached; show two of the more aquarium-difficult
Acanthurids... w/ a great deal of accrued body slime... exposed to what?>
and despite scouring the internet I've come up empty. I need some help in
determining what this is, and how to treat it. First of all, none of these
fish have entered my display tank - this pathogen has been confined to
quarantine. Also, I've now experienced it on three different fish
within three years. The first two fish (powder blue and brown
tangs) did not survive, despite months of attempted treatment and
troubleshooting with medications.
<Sans sampling and microscopic exam? Have you read the mat.s on WWM re
I have attached photos of those two fish for your reference. I had hoped to
never see it again, but now here I am. I ordered a Red Sea Regal
angel, and he came out of the bag with 4 of these "growths." I did
not attach a picture of the regal because I'm having trouble getting a
quality shot, and there is no doubt that it is the exact same symptom. What
I've observed, is that these "spots" start out as a small speck on the fish,
bigger than Ich and wrong texture/shape
for Lympho. They then proceed to "grow" outwards from the body of
the fish and form a 2-5mm filament that hangs off.
<... almost assuredly reaction from something "in/of the water"...>
I've seen them triple in size within a day or two.
<... mucus, mucin... See WWM re body slimes of fishes (these four words in
the search tool; on every page)>
On the deceased fish, I've attempted to remove the growths via tweezers or
scraping in hopes of learning something about them, but there's no real
anatomy as far as I can tell. They don't seem to be worms. I've had mild
results treating with .5mg/l Cupramine, but the parasite manages to return
worse than ever after a week or less of symptoms disappearing, while still
in full dose copper. I have not observed the disappearing act that is
associated with Ich, once a growth appears it stays; though the delicate end
piece can break off. Any help at all or insight you can offer would be most
appreciated. A regal angel is just about the worst fish to try and
experiment with medications on. Thanks in advance
<Am almost certain this is simply body mucus... a reaction to... something/s
in your water... Sample it and see (under a 'scope). Some treatment, an
aspect or more of your system is poisoning these fishes... causing them to
become "very slimy"... that's what this trailing white material is, NOT
parasitic; not pathogenic period. Treatment... involves investigating,
eliminating the source of toxicity here... salt mix? source water? some
"treatment" misplaced here... Bob Fenner>
Re: Need a parasite ID/treatment recommendation
Thank you very much for your reply Bob,
I had considered the possibility of excess mucous also, but there is
<The operative word... I WOULD add a unit or two of both ChemiPure (or
eq.) and PolyFilter in your circulation, filter flow path... likely
whatever this is... will be sufficiently absorbed to make a difference.
Going forward I strongly suggest you look about for a source of metal
poisoning (a fitting, piece of décor...) and sources of aerosols... ask
your water supplier (number on your bill) for their analysis of your
in my water that could be acting as a toxin. Is there something specific
you would have me check for? The obvious parameters are all perfect in
my quarantine systems and display - Ammonia, nitrite, nitrate are all 0,
phosphates are undetectable,
<... How are NO3 and HPO4 rendered as zero? Chemical filtrants may be
the source of trouble here>
I run my salinity at 1.025, temperature is 78 degrees. These fishes all
exhibited symptoms prior to any medication being introduced, and within
a day of being moved; including the regal angel which came out of the
bag from LiveAquaria this way.
<Am doubly concerned then LA has very good livestock... they buy
exclusively from the best outfit in the US... and several friends in
turn supply them>
The two tangs came from the tanks of fellow reefers where they lived for
years, but had never been quarantined previously. I am well aware of the
difficulty level of the tangs, and I currently have powder blue, powder
blue hybrid, and achilles all living quite happy and healthy in my 520g
reef tank. I attribute my success to quarantine. These particular fish
that showed sloughing mucous seemed quite random. Also, what am
I looking for under a microscope?
<Structure; send along pix>
Verifying that it is indeed mucous, or the nature of said mucous?
<Amorphous, almost clear, w/ some slight thread-like inclusions>
I will need to pick one up as I don't have one on hand.
<See WWM re>
I have managed to take picture of the regal, the "mucous" blends in with
the pattern of the fish unfortunately, each area is about 3mm long.
<Can't make out much more than this>
I realize the picture looks pretty mild, but after experiencing what I
have in the past with this thing, I'm nervous to say the least. I am
also unsure how such excess mucous would manifest itself the same way in
such soft bodied tangs and the thoroughly scaled angelfish. For now I
will focus on getting her a healthy appetite. Thank you for your help!
<Welcome. Bob Fenner>
Re: Ich or Velvet? 11/18/13
Thanks for all your help.
I have all fish in QT… and Kole tang died, one Chromis died… and it now
looks as if the ocellaris are on their way out.
I have been treating with Cupramine for 5 days now (and testing copper
levels). Began to see an improvement, however this morning the
clowns don’t look so good.
I have attached a pic of the female clown.
Could you help me in identifying the diseases/parasite?
<See WWM re... do you have a microscope?>
I though it was crypto, but now I think velvet. Shouldn’t
Cupramine have helped?
<.... IF velvet all would likely be dead. Looks symptomatically like
Cryptocaryon in this pic. Cupramine at proper levels should have helped.

Puffer with White Pimple looking thing on Eyelid
Good afternoon! Ok, so it appears that our Dogface puffer has developed
a white pimple spot on eyelid. I see no other marks or bumps on him or
any other fish.
<Mmm, just the one fish and one zot...>
Currently he is in a 90gall tank with a snowflake eel and a coral
beauty. We had an outbreak of Ich a few months ago and fallowed the tank

and everything seemed fine. But now, puppy the puffer fish has developed
this white spot on his eyelid. Is there any way to determine what
<Well; yes... but not worth doing in my opinion... take the fish out,

Parasite ID 5/21/13
Good evening WWM crew,
My hippo tang, flame angelfish, and clownfish may be infected <infested>
with a parasite that I'm having trouble identifying. I have only seen it
a few times on them, but they yawn a lot which leads me to believe it is
mostly in their gills. It is about the length of lead in a
mechanical pencil (a little smaller actually). I can just
barely see it, but I can tell that it is long and narrow, not
round. It does not move once attached until a few days later when it
disappears. The fish lose a scale or two (turns whitish/clear
and falls off) every few days. They have had this condition for a few
weeks and the severity is not progressing quickly, so I don't think it
is Ich. Any thoughts?
<Mmm, this may (just) be body mucus... some sort of irritation (many
possibilities)... causing the fishes to exude>
Might parasitic copepods be this small?
<Can be; yes... but are not oblong, worm-like, unless the host is very
large (bill fish, whales)>
I have tried treating with Chloroquine phosphate and Praziquantel to no
<Again; I'd do what you can to spiff up water quality here; see WWM...
water changes, chemical filtrants, RedOx improvement... Unless you get
samples, look under a microscope, I would NOT randomly medicate>
I'd rather not use copper in my tank. Do you think parinox will help?
Thank you for your advice!

Disease Identification... Marine Disease> Protozoan?>
Crypt?> ID f' 4/10/13
Hello WWM Crew!
I have a couple of questions regarding disease identification and
Tank info: Fish only, 55 gallons, 3 months old, Ammonia 0, Nitrites 0,
Nitrates 5, pH 8.0, salinity 1.010 (undergoing hyposalinity right now).
<... see WWM re>
Inhabitants: 1 Flame angelfish, 1 royal gramma, 1 Barrett's Anthias, 1
Striped mandarin fish (which is eating Selcon/Vita-chem. supplemented
Nutramar ova and can be fed pods from a culture I have if he starts
losing weight), and 2 tank-bred ocellaris clowns. All fish quarantined
for 3 weeks before introduction.
I know that hypo is not a great idea with clownfish, but I'm afraid my
fish may have Ich and, for moral reasons, I'd prefer to lose the
tank-bred clownfish because of hyposalinity (I'm happy to have paid
money to support this industry) than lose the wild-caught flame angel
because of copper.
<There are other (better, more effective, sure) treatments; i.e. quinine
compounds. See WWM re>
I've been watching the clownfish and they are very lively with good
appetites. Hypo treatment has been going for 5 days now. Would you
please help me diagnose?
<Need samples and a microscope... all else is guessing>
Symptoms consistent with Ich: small .5-1mm spots that disappear in a few
days, spots do not move from place to place on the fish, somewhat rapid
breathing, visible on all fish (each fish only has between 1 and 5
visible spots but this number is growing slowly), no excess mucus being
Symptoms that don't match Ich: the spots are more of a greyish/white
translucent color, growth in number of spots over time seems slower than
usual for Ich (although this may be due to the hyposalinity treatment
limiting them), fish are not scratching on rocks but do twitch on very
rare occasions, all fish have 1 or more spots, spots are located on the
body but not on the fins (yet).
I already treated the fish with general cure (Metronidazole and
Praziquantel) during quarantine, so I don't think worms are the issue.
Do you think the fish have Ich or something else?
<Can only guess w/ what is presented. Again, simple enough to do a real
look/see... from what you describe, these markings, mucus could well be
just body slime, reaction to the med. exposure, handling and low spg>
If so, I'd rather not treat with copper... After doing a lot of digging
and research, I have found some info on Chloroquine Phosphate and
Quinine Sulfate (Crypto-Pro).
<Ah yes; preferred treatments currently>
From cruising WWM, it seems that you prefer Chloroquine Phosphate out of
those two. Do you think that this medication will eradicate whatever
protozoan/parasite my fish have?
<... I would NOT treat them, these fishes, w/o sampling and examination.
ALL treatments are toxic, debilitating in kinds, degrees>
Also, can it be combined with hyposalinity? If you think I should just
do hypo, I'd love to know that. But I'd still like to know if CP or QS
is safe in combination with it. I know copper is not. Finally, does
either CP or QS stain aquarium sealant, decorations, etc? Since the tank
only contains the fish, dead base rock that was bought dry, and
nitrifying bacteria that I added from the brand "Stability," I'd like to
treat that tank.
Thank you for you advice and this wonderful resource! Sorry for the
lengthy email. I have realized that attention to detail is essential in
this hobby. Brielle
<Welcome little Bri. Bob Fenner>
Re: Disease Identification– 04/10/13
Thank you for your advice, Bob! I'll stop the hypo treatment and
continue to watch the fish/not treat them. I am hoping that you can
answer the last questions on my email though, in case the symptoms
worsen. I have had saltwater fish before (about five years ago) and they
died from an Ich outbreak because I didn't know how to handle it.
<This is, unfortunately, the "end" to many salt water aquarists
involvement in the hobby. Worse/worst for the fact that if people in the
collection to wholesale ends of the trade would employ simple pH
adjusted freshwater dips/baths, the vast majority of such infestations
would be avoided>
I would love to have the proper knowledge/medications on hand, since I
have to order meds online and know they take awhile to arrive. I know
Ich is very common, so since I am still quarantining/introducing fish to
this tank, I'd like to have the proper med. on hand and the knowledge on
how to use it correctly. Your thoughts are much appreciated!
1. Is Chloroquine Phosphate more effective than Quinine Sulfate?
2. Can either/both of these be combined with hypo?
<Not really; no>
3. Does either CP or QS stain aquarium sealant, decorations, etc?
<Neither do; though semi-semi-relatedly they're both better applied in
lower (less bright) light settings>
4. It seems that these two meds harm the biological filter somewhat, but
don't completely disable it. Is this true?
Again, thank you so much for your help!

Hi I'm looking for a little help with an ID. Some background on the
Began as a 72g with un-quarantined fish. Majestic angel,
<... needs more room than this>
flame angel, 2 maroon clowns, exquisite wrasse, cleaner wrasse,
<... inappropriate species here>
Everyone has an opinion I guess, I've had him for 6 months and he eats
everything I put in the tank. My opinion is if you keep one, it needs to
fed 4 times a day or more to stay healthy.
>> Mmm, yes. Much has been written re Labroides captive use...
particularly L. dimidiatus... most (90+ % die w/in a day of collection.
Some small part of one percent live a few months in captivity<<
Fiji blue damsel. After 2 days, Exquisite wrasse got some white fungus
cottony looking patch and died within a week despite eating well. All
was fine after that so I don't think that was related. I did add a
hectors goby some time after and I began seeing some spots on my clowns,
but none that looked like Ich. These were more cottony/fungus looking.
Some other fish
(majestic and cleaner wrasse mostly) began scraping on rocks. Majestic
got some large white patches I almost thought could be velvet and died
within days. At that time I broke down the tank, thinking I had Ich and
not really sure if/what else.
* Not a tear down per se, I had to take it apart and re organize to
catch the fish. Broke it down was not the right term.
I used tank transfer method. *
<What is this? Leaving the intermediate states of parasites behind?
Dipping/bathing fish/hosts enroute?>
* I'm rather surprised if you haven't researched tank transfer method
for crypto. I have faith that worked and it only makes sense that if you
move the fish to a brand new tank every 3 days, all the parasites have
to eventually drop off the fish to complete their life cycle. 3 days is
not enough time to drop, cyst, hatch and reinfect the fish. Within 3
transfers the fish should be crypto free if the method is followed
>>Am very familiar w/ various ectoparasitic exclusion techniques... just
wanting to be clear, prompt you to describe for the many browsers who
will read your posts over the years<<
to treat the remaining fish, and I had a newly set up 125g with only 2
fish (dogface puffer and a juvi red Coris). The dogface puffer I was
also sure had Ich, and so I caught these two and treated them with the
rest from the 72g. I set up a 20g which I already had cycled, and used
that for the wrasses. treated with Cupramine (3 wks) and then PraziPro
<Why the Prazi?>
*Why not? fairly safe med for all, and puffers are known for internal
parasites Prazi is good for. *
The rest (Puffer, flame angel, 2 clowns, Fiji damsel) as I said I used
tank transfer (I did about 6 or 7 transfers 3 days apart using 32g trash
cans bleaching and drying in between).
<... won't work>
*Why? It seems to make a lot of sense compared to the crypto life
>>... see WWM re... Or just wait/see. The stress of moving fish hosts,
No signs after that and from there they went to a 90g qt that I cycled
specifically for these fish. I did not see any signs on them from here,
but I did treat with Cupramine for 3 weeks to be on the safe side, and
then one week of Prazi. I left my 72g and 125g fallow during this time,
but I did add snails and some coral frags in the mean time. I went about
8 weeks with no fish but I did add some snails to both tanks only about
2 weeks before reintroducing fish. The flame angel and cleaner wrasse
went back to the 72g and seem fine.
The 2 maroon clowns, puffer, Fiji damsel, and red Coris went back to the
125g. That was about 3 weeks ago. Last week I noticed a small white spot
on the larger maroon clown near the dorsal fin. That is in the first
I kept an eye on it but there was no other signs of anything on the fish
or any other fish.
All of a sudden this morning the larger maroon clown is now covered with
similar spots as the first. I really don't think this is Ich, as usually
when I see it I can id it very easily with certainty.
<Can't w/o sampling, microscopic examination>
* Not much I know of that looks like it besides velvet which you would
find out much faster that its not if that were the case. *
>> See Ed Noga's works... Can be downloaded via the Net for a fee<<
These spots are irregularly shaped, and all over. Some on their lips,
very edge of some fins, and on the body. There is one spot that is
larger than the rest near the clowns dorsal fin which almost seems cone
shaped but fuzzy looking. All the other spots are fuzzy looking and
around some the skin seems somewhat darker in the immediate surrounding
<See WWM re marine parasite ID> * I probably should have mentioned your
looking at a 4" clown, and those clumps are sesame seed size or bigger,
not salt sized.*
>> I see... take a look on WWM re Amphiprionine parasitic diseases;
there are images, good descriptions<<
I took a lot of pics to try to show this but you can only see so much in
a picture. The best pics I can find online seem like brook but I can't
tell because it seems so different in all the pics I see. Also I would
think if it were brook they would all be dead by now. I tried to send
image links for the pics if it doesn't show in the email then you should
be able to paste the links in your browser. Also Parameters are 1.025, 0
ammonia, 0 nitrite, 5-10 nitrate, 1200 Mg, 400 Ca, 8 to 8.5 dKH in both
Thanks for any help. Dave
<Does look like Crypt... on the Premnas... in a badly bleached
anemone... but what to do? Read:
and the linked files above. Bob Fenner>
*anemone isn't bleached, it is green, bad cell pics, camera doesn't like
leds much. I am thinking that it is some sort of fungus/fin rot type of
disease. No other fish are affected still at this point. There are
several more clumps on him not and some look to be eating away at the
fin. I attached another photo. Look at the rear of the adipose fin.
About 3/16 of an inch now is eaten away there. Fish still eats well too.
Anything I can try to use in the display? It wont be an easy task to
catch him, and I have new fish about half way through their qt process
in 2 qt tanks. So convincing my wife I need to set up a 5th aquarium
won't go well.

Chloroquine Phosphate treatment... 3/1/13
Hey Bob, does it make sense to you to see a few spots of Ich or velvet
on my powder brown Tang exactly one week into CP treatment?
<... can't tell from "just looking" (i.e. w/o a microscope, sampling...)
what spots are. May well be simple body mucus accumulation... from some
sort of irritation... even the CP. B>
I dosed exactly what is recommended (40mg/gal).
re: Chloroquine Phosphate treatment...
Ok. I see where your coming from. I've been in the hobby since 2005 and
I've had my share of both Ich and Velvet. I know that it's definitely
one of the two and I'm leaning toward velvet. If in fact it is velvet,
is it normal to be showing up on fish after the CP has been in the water
for a full week??
<... see WWM re Velvet/Amyloodiniumiasis... all your fishes would be
dead by now. Don't write: read>
re: Chloroquine Phosphate treatment...
Ok. But a yes or no answer would have been a much shorter and easier
answer than the angry one you typed. Short and sweet Bob.... Thanks

fish worms - 10/28/2012
Bob and Family, Its Jim again! I hope you all are well, and it has been
a while. Well life in the marine world had been very good for several
months, Until lately. Over the last month or so I have lost a few fish
here and there. Bi-color goatfish, fairy wrasse, and a raccoon
Butterflyfish. They were always eating and got skinny. I figured they
have some type of internal worm. Somebody told me to use Praziquantel
and mix it with my food. I am not sure if I have been doing it right. I
would take some Mysis and put a little in and mix it. Some fish like it
others don't. I have been noticing my Queen Angel is not fat like my
other Angels and she is a pig.
When she poops its brown on outside and white in the inside. I was
thinking of hypo salinity my tank to kill the worm, but not sure if hypo
will work considering its internal. Please help, Jim
<Well, if many "different" fishes are involved... and the thought is
that this issue is an internal/lumenal parasite... I'd be more inclined
to treat for Protozoans... as in w/ food laced w/ Metronidazole.
However, there could well be other issues that might well show up per
the symptoms you list. I'd do a thorough look/see re your water quality
first, ahead of treating w/ anything here. Bob Fenner>
re: fish worms - 10/28/2012
Bob, Thanks for the quick reply. My water quality is great. I do 25%
water change weekly. I change my charcoal, and poly filter every two
Nitrate, ammonia, nitrite is zero. Ph is 8.27
<Well, these values are fine. Am wondering how you render the NO3 as
zero though... And I would only change our the carbon once a month...
Re: fish worms - 10/29/2012
Bob, My NO3 has been zero for months. Why would it not be?
<Most folks, situations "over-drive" nitrification... the most
prevailing condition is for production of excess nitrates>
I have a nitrate reactor. Its keeps my nitrate at zero and phosphates very
<Ahh... the reactor; yes. THIS is likely the source of the skinniness of
your fishes, not worms>
I change my charcoal every few weeks because the instructions say so.
<Too much GAC activity too can be problematical. I would cut back>
I buy the pelleted Foster and Smiths charcoal. I just ordered a tds
meter to check my ro-di to make sure its working its working right. I
respect your opinion Bob, but last time when we were talking about water
quality when I had fish dying one after another. You said this before
and I listened to you and James. I had my whole tank crash and lost
$3000 worth of life stock. I told you guys that I read it could be
flukes and you went back to water quality. Well it turned out to be
flukes. Now I am not saying that it was your fault, because its
not. It was mine for not quarantining my fish when I got them. I do
quarantine my fish now before I put them in main display. I never
Prazipro my quarantine, because I saw no signs they needed it. I
do think it is some kind worm because a few of them eat like crazy, but
never gain weight. I have a few other Angels and they are fat like
angels normally are, but my queen is pretty skinny. Jim
<The final decision (as in nothing is decided till it's done) is up to
you Jim. I/we can only proffer our input based on what is related and
our knowledge/background. B>
Re: fish worms, Using WWM 10/30/12
Bob, Wow my nitrate reactor? Could you please send me a link so I can
read about it?
I hope I did not offend you Bob. I truly think you guys are great and
appreciate your advise. Jim

search about for others. I urge you to learn to/use the search tool on
WWM... using key terms that make sense to you. B>
White spot for a day, SW 7/28/12
My 55 reef tank is 7 years old and I have various fish in it.
Recently I have noticed on a couple of the fish 1 or 2 white spots on the tips
of their fins or on their heads.
<Mmm, could be a few things... not necessarily pathogenic>
The spot lasts a day and is gone the next. I thought it might be, for lack
of a better word, "snow" but the spot seems to last most of the day.
<Mmm, could be a "trace" of a Protozoan (e.g. Crypt) issue... often are
transient if there's a "balance" of health in a system>
I do have a history with Ich so I don't think it is that.
<I wouldn't be, am not so sure>
This has been going on for about a week. I've only seen the sleeper
goby "flash" one time but I don't see any foreign spots on him.
<This group is more resistant, slimier than many other fish families>
I did add porcelain crabs over a month ago after they had been in the QT
for 3 weeks. Does this sound like a disease?
<Can't tell w/ the information presented>
The spots are very small, uniform and not lumpy. Please let me know
what other info you may need. Thank you Jennifer
<I'd just keep the system optimized and stable. Please read here:
and the linked files above. Bob Fenner>
Re: White spot for a day 7/29/12
Thank you, Mr. Fenner. I will just keep an eye on them. I just
didn't know if there was something viral/bacterial that could present as white
spots for a day, which I know if vague but that's really the only symptoms they
are experiencing. Their appetite has not changed. Again, thank you
and I will just keep an eye on them. Jennifer
parasites ID 6/28/12
Ladies and Gentlemen,
Hope you are all doing well.
I have a Flame Angel, two Chromis and a Copperband in quarantine ( 20
USGL ). On week 2 the Copperband showed two like Gyrodactylus on dorsal
fin ( see yellow arrows in pic ) 1 mm long and whitish in color.
They grown from non visible to a 1 mm in length in 2 weeks. See picture
After a Formalin dip ( 50 min ) the parasites did not detach.
So, once back in the quarantine I manually scrapped them off.
Unfortunately they dropped in the container that I used to maintain the
fish underwater and still.
In the bottom of container I gathered specimens B and C.
B was hard, stiff in texture and looked like a shrimp like bug but with
no legs, more like a worm or cyst. C was more like shrimp. When I
scrapped them off I must of released a bunch of parasite nauplii that
were swimming around
( see arrows in red ).
Unfortunately with all the hassle I was only able to mount C in
the microscope, B is only seen through a magnifying glass.
This scenario has me worried and concern about a future probable heavy
infestation. My Quarantine has a 8 w UV & I do 2.5 Gal water change
every 48 hrs. The butterfly and angel do not scratch but Chromis flash
/scratch on the side of the butterfly (????).
It looks like a have a zoo of parasites in that quarantine.
<At least a few>
Since a had BAD experiences treating with Cupramine in the past with the
Flame Angels ( they died ), that I do not know how the Butterfly ( my
fists and very dear one that is FINALLY EATING!!! ) react to all of
those treatments and that I have never done a Hyposalinity
process, I would like to know with the info that I shared with you
here.. what is the best course of action. The fishes have already gone
<Prazi/quantel for the worm/s, yes>
Metro and Kanaplex prophylactic. Should I do a hyposalinity, Cupramine
or long term Formalin treatment? How long?
<No to all these others, but do add something for the Crustaceans. Read
Bottom line : What would you do. Please recommend.
<Treat w/ both an organophosphate and Anthelminthic... and soon. NONE of
the other materials you list>
Thanks again for all the help.

Bob, Thanks for your Mail:
As per your recommendations I am starting the Anthelminthic treatment with
Praziquantel for 5 days and after that with fluke tabs ( one time ) as the
Do you think I chose the correct medicines?
<I do... just to check... there are no invertebrates present correct?
Including no live rock in the QT>
If not please recommend.
<A lack of resp. will serve as affirmative for the above. B>
I was hoping that maybe you guys could give me some advice on
what to do next with this fish. He has what appears to be
an external parasite on his soft dorsal fin (see picture).
<Mmm, I see this white dot>
Now the fish has been in .21ppm Cu for a week now (since i
received him in) and was just yesterday put in a freshwater dip
with Methylene blue for 10 minutes.
Still the spot does not seem to be changing. Any thoughts
or idea on where to go from here?
<Yes... into the main/display tank. This is not likely a
parasite at all... but a blem from a reaction/bent fin
He is in QT (although with a few Chromis as well). I do
have an empty tank that i could set up for another QT if you
think i should change up the copper with something else (not sure
how well copper treats these guys). What do you guys
think? More of the same (with a few more dips) or something

Identifying Parasites from FW Dip 2/14/11
I have a red Firefish in a new 29 gallon FOWLR tank. He's the only
fish I've purchased so far, so I didn't do a quarantine, and
being new at this I wasn't confident enough to do a FW dip. Over
the five days that he was in the tank he was dashing his head against
the sand about once every ten minutes...clearly an itchy fish! I
thought it might be a gill infection (Ich, velvet, gill flukes...?)
<Mmm, perhaps. Much more likely though "something"
disagreeable w/ water quality>
I caught him and did a FW dip. Almost immediately about a dozen white
bumps started swelling on his body, and fell off. They were about a
millimeter in length, and shaped like slightly elongated disks:
in one dimension, and elliptical in the other two dimensions. Based on
the size and shape of these things, can I rule out velvet or Ich?
<Mmm, can't say from the description; but not likely
Protozoans... more likely Flukes>
I don't know how big the velvet or Ich parasites are when they fall
off of a fish during a FW dip, but I'm guessing they may be smaller
<Yes. If anything, they might be incorporated in w/ body mucus to be
this apparently (large) size>
Assuming these are some type of worm or fluke, what do I do now? I have
the fish in a hospital tank, of course, and plan to repeat the dip a
few more times over the next few weeks. How long should I let the
display tank remain fallow to have a good chance of starving out any
juvenile parasites that may hatch? Thanks!
use the search tool, or the indices. Bob Fenner>
Re: Identifying Parasites from FW Dip 2/14/11
Wow, you even got my name right! Almost everyone misspells it as
Before I emailed you I checked the FAQs and found a recommendation of
"at least four weeks" for a fallow period following a fluke
infection. I'd love to think I can get away with just a month, but
I'm skeptical since this is the answer I want. I know, of course,
that there's no sharp cutoff that identifies the "right"
fallow time. Even if one could positively ID the parasite there's
just a law of diminishing returns that kicks in after a while. But even
without absolute certainty, I have to make a decision to put the fish
back in the tank on some particular day. If you can, I'd appreciate
it if you could check my logic on what to do next.
First, I assume that this is a metazoan parasite, so doesn't bury
itself in the fish's tissues like some protozoa, and therefore at
least part of it is exposed to the ambient water. Based on this and
what I saw, I conclude that FW dips are very effective and also
diagnostic against this parasite. That is, if there are any
"flukes," I'll see them puff up when I do a dip.
Therefore, I plan to re-dip the fish after about 2 weeks. I expect that
watching the results will tell me whether there are any flukes still on
the fish. I'm hoping the first dip was effective, so that the fish
will be clean. If this is the case, after two more weeks I plan to
replace about 30% of the water in the hospital tank with display tank
water, maybe even including some sand from that tank. If there are
viable parasites in the display tank, I expect this will re-infect the
fish. After another two weeks, I'll do yet another FW dip, and look
for parasites. If I don't see any, I'll declare victory and put
the fish back in the display tank. If any of these steps don't give
the results I want, it's back to the drawing board. Does this plan
<Sounds good! BobF>

that I treat with a product called PraziPro because my Butterfly was
flashing (he said, based on what I told him, he probably has gill
I started treating with the Prazi and ever since then my BF has
increased rapid gill movement and twitches a lot.
If in fact he did have flukes, I thought the Prazi was supposed to help
kill them.....why are they getting worse?
<Are they flukes? If you remove the fish and freshwater dip him, you
might see one or both of two things that would give you a better idea:
If he stops flashing afterwards, then it is probably flukes. If you can
see specks on the base of the dip container (usually white, so a dark
dip container might be prudent), then they also could be flukes.
Removal of these and placed under a cheap microscope will confirm. If
neither of these happen, then it is probably not flukes>.
He has been clear of spots for over two weeks
<Could have just cycled off... the fish may still be infested with
Crypt.. in the gills, thus the heavy breathing & flashing>
and I proceeded with the full treatment recommended for QS. Please
<Another possibility here... medication in the water can/ does
irritate fishes, to the point where they exhibit 'flashing'
behaviour. You might find that with the removal of the medication and
improved water quality this will ease off>.

You have a wonderful website with a great deal of great
I have a 165-gallon tank that has been up for 3 months. We have 1 clown
trigger (4 inches), 1 nigger trigger (3 inches), 1 yellow tang (5
inches), 1 blue hippo tang (4 inches), 1 raccoon butterfly (4 inches),
1 yellow head goby, and 1 dragon goby (both 3 inches).
The water measurements are ph 8.2, ammonia 0.00, nitrates .20, nitrites
0.00, and hydrometer reads 1.022. The temperature of the tank ranges
from 78.9 to 80.9. The tank has live rock and sand. We also have a 65
gallon tank that had been up for a year.
<Don, Thank you for providing these details. Also, while everybody
gets along now and everyone 'fits' in this tank, you are likely
to have some behavioral problems down the road.>
Yesterday my powder brown tang looked like it had swam through a snow
storm. It started swim in small circles and refused to eat dinner.
Within about an hour he was dead.
<That is fast - too fast for Crypt. How long did you have this fish,
how long was it quarantined, and how was it behaving recently?>
This is the first fish that we have ever had that has died. I had just
did a 35 gallon water change the day before and moved the direction of
one of my powerheads more at the rocks. I buy saltwater from my LFS
same place I have been using the last year.

Re: Trying to save my clown (trigger): SW Velvet. Disease
identification and treatment. 8/3/2009
Thank you for the very informative links. After spending almost all of
Friday reading thru your website and every link on Google, we would
agree we have VELVET.
<Need to treat and treat fast.>
So we went to our LFS and bought something they said works well and
they run in their tanks called Copper Power.
<Ok, do realize that you need to use copper long term for it to be
effective against this disease. It will get it off of the fish, but not
kill it in your system.>
When we got home it was about noon and our clown trigger still
hadn't showed up. We truly believed he was dead since he missed the
morning feeding and we couldn't locate him anywhere.
Our QT tank is only 20 gallons and at this point now the raccoon
butterfly, hippo tang, and Niger trigger, all were showing signs of
this powder across their bodies. The raccoon looked by far the worst.
As I stated we have a FOWLR tank and getting these guys out would have
created a huge stress and we have no doubt would have pushed the
raccoon over the edge. We still knew we were going to have to located
the clown trigger body and remove it before it started messing up the
water. We decided to treat the fish in the main tank hoping to
stabilize them and possibly get them back on a road to recovery.
<Ouch!. This is going to kill any invertebrates as well as your live
This may have been a dumb thing to do but we felt it was like trying to
stabilize an accident victim before moving them, so they don't die
on the way to the hospital. This may have been flawed logic on our
part, but I just didn't want anymore lose of life.
If they start looking better in a week or two should we move them to
the QT and treat again?
<Treatments are best in a QT tank, as the tank has been
'nuked' at this point, start watching your ammonia levels - the
copper will kill off your biological filter as well..
About four hours after the treatment of Copper Power to the main tank
the clown trigger appeared. He still was covered with the white powder
looking stuff but was swimming around. We were filled with joy and felt
some sort of huge victory.
<Copper starting to work.>
Since the clown trigger didn't get breakfast we fed the fish again
a small amount of food and all of them had great appetites. As the
evening went on we noticed the raccoon and clown trigger going to the
top by the overflow looking like they were trying to get more air.
<Gill damage from the velvet.>
So I adjusted the power head on the opposite site of the tank
completely upwards to create a large break in the surface. I also add a
12inch air stone to the other side of the tank. We had also unplugged
the main display light to keep the tank darker.
At 9:00 PM we fed them again and all of the fish ate. It appeared about
15 min.s after eating all of the fish retired for the night.
This morning at 9:00 AM we did a count and couldn't find clown
We lifted the lid to the tank and got all of the food out and
About 15 minutes into this the Clown showed up. From where we still
don't know. We then fed the fish. The sad thing in this time the
clown or raccoon didn't eat. The raccoon still is covered with the
spots and now is hanging out next to the air stone and the clown went
locked into a rock facing the bottom if the tank. We are seeing very
little movement from these two as I write this.
<Not a good sign. Velvet does kill quickly.>
The other fish are swimming and ate well. The gobies still have not
appeared yet, but they usually don't until the light comes on.
The tank is dark, temp is holding at 82.9, the salinity is 1.022, water
circulation is good, and I added about 2 gallons of r/o to sump this
morning since it was low.
Did I create more trouble by treating the main tank and where should I
go from here?
<Well, it didn't help - all of your live rock is now dead or
How long until we should see signs of improvement?
Can take a while, velvet infests the gills long before you see signs on
the fish itself.>
Can velvet be killed by not leaving the tank without fish for 6 weeks
and just treating with copper for that long? Or does that just
<Copper is good for getting the velvet off of the fish, but it will
not kill it in the tank unless you continuously dose for weeks.
Chloroquine diphosphate is a much better solution. Try
Thank you again for your great articles and willingness to help. Once
we get through this no fish will ever go in any of my tanks without at
least a 5-week QT.
<Sadly, it usually takes a lesson such as this.>
Re: Trying to save my clown 8:00 PM update part 2
<Hi Don, Sorry for the delay in writing back, had a minor
catastrophe at my house as well.>
Good evening Mike. I just wanted to give you an update and ask for
All today we kept the lights off in the tank. Since this morning the
clown trigger remained in the rock face down and never moved. We also
cover the tank with towels to keep it as dark as possible. At about
6:00 PM we fed the fish again, the raccoon butterfly ate really well
<A good sign.>
After the food had been in the tank for about 2 minutes the clown
trigger started moving and slowly came out of the rock. So we added
some omega brine shrimp so the clown could have the opportunity to eat.
He did start eating and appeared really hungry so we added some more
food and he ate that also. He had a really good meal. He swam around
for about 15 -- 20 minutes and went back to the rock he was in all day
and positioned himself facing the bottom of the tank again.
<Good sign that he is eating. It will take a while for him to
At 8:00 PM we used a flashlight to check on him and he is breathing
very slowly. He doesn't appear to be laboring. While he was out
swimming and eating it appeared some of the dust or white that was on
is body was gone and in its place was what looked like a sore or an
<Yes, do watch for secondary infections.>
Also when he went to the restroom his waste was white and stringy. He
relieved himself twice and both time the waste looked the same. In the
four months we have owned him this is the first time I have seen him
<Likely because you hare hyper-aware of his health.>
After spending the majority of the day next to the air stone bubbles
the raccoon butterfly is now actively swimming around and picking at
the rocks. All of the other fish appear to be doing well and are eating
at each feeding.
The tank is dark, two air stones now in the tank, circulation good,
temp 83.7, salinity 1.023.
What else should we be doing?
<Watch for ammonia, I am expecting your tank to cycle again.>
Thanks again for all of your help.
Parasites in Reef Tank-- Nope, Just Copepods.
My question is about a parasite outbreak in my reef tank.
Most of the questions on your site in this category involved
fish, but I do not have fish in my tank, just cleaner shrimps and
snails. My tank is a Red Sea Max 250 (65 gallon) with a
built-in protein skimmer and has been up and running for three
months now with a mix of Fuji and Tonga live rock, and a
<Ok so far.>
The other day I noticed a white out of dust-like particles all
over my tank. These things are also moving on the back of the
tank and in my opinion appear to be a parasite.
<No, just Copepods, read here:
They are also suspended in the water due to the robust water
circulation. Will they cycle-through and just die off in a
few days or do I need to medicate the tank (which everything I
have read screams NO for reef systems).
<Do not medicate, since they have no predators in the tank,
the population has exploded. It will settle down in time.>
I do not plan on adding fish and will only have a few corals.
Thanks for any advice you can give me.
<Patience is all that is required.>
Black spot, maybe not 12/26/08 Hi
there, <Hello Dan> Sorry to be a bother, but I have a
confusing situation over here. I have a 90 gallon reef tank with;
yellow tang, blue tang, two clown fish, anemone, clam, cleaner
shrimp, sally light foot, purple lobster, leather corals, hammer
corals, some polyps, mushrooms and other bits and pieces. As well
as about ten, well established mangroves growing in my sump
refugium. Everything was going quite well until I added a yellow
eyed Kole tang (which I do love) to my reef. Two weeks later I
noticed black bumps and some color fading appearing on my blue
tang. As well as some lateral line and forehead peeling on my
yellow tang. So I went on the Internet and found your site. I
think my blue tang has the black spot disease, <Mmm...
actually... you would very likely see this now, concurrently on
the Yellow, Zebrasoma flavescens... I think you may be witnessing
Microsporideans... not really treatable... and not very
debilitating> but I didn't notice any info about the spots
kind of bumping out a bit, <Good description... and likely
shiny, kind of shaped like cones... whereas Paravortex is dull,
flat...> and one day he was fine and the next he has 20 spots
on him. So I am guessing I need to quarantine him, but what about
the Kole (who is fine except for only eating off the rocks so
far) and yellow tang? <Again... or for emphasis, I would NOT
move these fishes... at least as yet...> I think I can deal
with the yellow tang as it seems as his peeling is do to poor
water quality <?! What leads you to think this?> and
stress. I am about to do a water change and hook the skimmer back
up (after two years off due to the mangroves). <I would>
Should I quarantine all of the tangs? can I do them all together?
What product would you recommend? <No, yes, None> Could I
do it in my mangrove tank or will the medicine possibly hurt
them? <Depending on what's used, yes> Sorry again and
thank you for your help. I have never had a sick fish before and
was upset to see him, I do have a good photo if needed and also
don't know how to find this page again. <Mmm, should be
here with your message/response. Please do send the image
along> Thank you Dan <Welcome. Bob Fenner>
black spot, maybe not 12/27/08 Hi there again
Bob. <Dan> I was worried about waiting another day to treat
my fish, so I made a executive decision and went against your
advice to wait to move the three tangs into a quarantine. I see
why you said wait as it does seem to cause a lot of stress (for
the fish and my girlfriend and I) to try to catch them. I was
only able to catch the infected blue tang, but did so without
disturbing my reef which seemed good as I have seen what happens
when you start moving rocks around. I went to my LFS and showed
them the same photo of the blue tang I sent you, <I still
haven't seen this image> and he told me to quarantine all
three and to treat the fish with aquarium Munster proto Marin
Intensiv, <What are the ingredients here?> which I did do.
I was reading the instructions and noticed that it said nothing
of treating black spot or Microsporideans. I know I should have
waited until you saw the photos but he seemed to be getting worse
and I wanted to get him treated as soon as possible. I have the
feeling I am not treating him with the right medication. What
should I do now? <...> I know you will have probably
answered all my questions in my second email but just in case,
should I keep treating him with the proto Marin, and if not than
what? >... nothing< should I catch and quarantine the other
tangs? <... already answered> What about the other fish?
<... How would I, anyone be able to determine what is actually
going on here?> I have been reading about dips - would you
recommend doing this? and should I keep my fish quarantined for
4-6 weeks? also I have a Marineland hot magnum that came with
cloth like filter like those in vacuums, would this work for my
hospital tank? or if not could I fill it up and run it with the
sponge filters? Sorry for going ahead as I have read some of your
articles where people did the same thing and they seemed
annoying. Also sorry for two emails at once, I just wanted to
keep you posted and if you thought the blue tang would be better
off back in the reef tank, another day would not have gone by.
Thanks so much for all your help. I appreciate it. Dan. <...
Please, see, read on WWM re Acanthurid Health, Protozoans,
Infested Systems... B>
black spot, maybe not 12/27/08 Hi Bob Thank
you for getting back to me so fast. What lead me to believe that
the yellow tangs peeling is do to poor water quality is that, It
had happened to him before and when I started trying to improve
my water quality it went away. He may have started peeling before
I introduced the Kole tang, and I have noticed that a lot of the
yellow tangs in LFS do have the same problems. I guess I
diagnosed him with the head and lateral line disease. I did have
a few mangroves slowly die in my sump a few months back when on
vacation, and when I questioned the guy at the LFS about his
peeling he guessed that my nitrites were high, which they were,
and said it generally happens when water quality is low and they
are stressed. Do you think thou I could be wrong and my yellow
tangs problem could be related to the blue tangs black spots?
<Mmm, indirectly, yes... the pitting is very likely mostly due
to "poor water quality"... is a type/form of
HLLE...> I should mention that all of my fish are acting
normal and are as hungry as ever, thou I have noticed the blue
tang rubbing a bit on the live rock. I couldn't find any
information on Microsporideans. Will my other fish be affected if
I do not quarantine the blue tang? I read some where to remove
activated carbon, I run Chemi-pure in a hang on filter should I
switch it off or change products? <... I would keep using the
Chemi-pure> As for the blue tangs bumps, on the blue part of
his body there are bumps with a black spot in the middle and
around the spot on the rising sides of the bump seems to be
whitish. However on his black markings he seems to only have one
or two white spots, and on his fins and tail just black dots no
bumps. Does this sound like Microsporideans? <Could be...
but... net cause/s?> Is there anything I should do? Hopefully
the photos are usable and helpful. Thank you very much for your
time Dan <Keep reading. BobF>
Cont.: Crypt and, God willing, the lack thereof?
12/3/08 Dear Fishmasters of the Sea... And, specifically, Lord
Fenner for helping me last time (I tend to envision Bob in a loincloth,
perched above a raging sea, commanding the ocean's minions with a
simple wave of his trident... But, that's just me) <Heeee!
Replace the trident with a Kona Brewing Co. IPA and I'm there!>
Thank you very much for your reply. "Be chatting" is a good
sign from what I've read! I will spare you the string from my last
email, as it mostly contains random observations and stories from my
childhood. If this is Bob, I wrote you about my Louti and Panther
Groupers, Foxface and Humu Trigger... All Thrown in my 100G without
quarantine... <Ah yes... I do recall> Thought I had Ich/Crypt...
Again, I have read darn near everything pertaining to the following
questions... I get it - The information is there. I also get that
different people have had different successes and failures with varied
procedures and approaches. <Ah, yes> Perhaps it's my
indecisiveness and need for a straight, definitive answer, but the
seemingly contradictory advice is making me cuckoo. Options are not
good for me. I have a 2 month old 100G FOWLR with approximately 100-125
lbs of Liverock, 3" Sandbed (will soon add 1-2"), Wet/dry 30G
sump, AquaC Remora producing half the cup of daily, semi-dark green
skim... 2x96PC lights on 10hrs... Ammonia-0, Nitrite-0, Nitrate
possibly 10ppm, PH-8.2, Spg.024, Temp at a very stable 78-86 (Heat wave
last month was killing me, so I didn't bother using the heater...
Error... Adding fans has kept it under 80-82... Since it's now
freezing in the morning, I just set the heater to 80 even. Nowhere else
to go). <Good> Everyone is eating well and seem to be getting
along. Have had Louti(5") and Foxface(4") for a little over
thirty days. Panther(4") and Humu(2") for about two weeks. I
know their personal, given names are probably not necessary for
diagnosis - But I sure do love watching "Guerny" screw up my
tank! Guerny is short for Guernica, as he is a Picasso Trigger... (Is
anyone getting my art/fish reference?) <Mmm, yes> I'm
actually only pretending to be this annoying... I don't NAME my
fish! So, a few days ago, Foxy looked like he had two little white
granules on his side. A few minutes later, they were gone. Now, I may
have dismissed them as sand or air bubbles (have read WWM post from the
man who misdiagnosed bubbles as Ich), were it not for what appeared to
be two tiny holes in the same area. I have read that this particular
fish tends to produce excessive slime coating (have seen it floating
around). <This is so> Could this have been some sort of parasite
that was easily/temporarily sloughed off? <Could be... but might be
spurious> Shortly after, I may have hallucinated extremely small
specks on Dr. Grouperson's fins, but it's so hard to tell on
the translucent pectorals of this Louti. Nothing elsewhere on his body.
Nothing whatsoever on Dot (aptly named Panther Grouper). And lastly, I
really cannot tell with the Trigger... Twice, he had what looked like
something on him, but... He spends most of his time digging and
spitting out sand. He's got quite the tunnel under the rock... Same
routine - swim around the back, come out the front, spit into sand
mountain. (I'm half-waiting for him to come up with woodchips from
the stand). In all seriousness, he does spit sand everywhere and on
everything, including tankmates... Could that be sand I occasionally
see on Foxy and himself? <Yes> Last night I turned the lights
on... Everyone was asleep. I saw a white speck on the Rabbitfish and,
so help me, it moved about an 1/8th of an inch (didn't fall off).
Is that possible? <Yes> Could it be a Copepod, as they are
everywhere in this tank (particularly where Foxy was sleeping)?
<Maybe> My LFS guy told me, point-blank, "Treat in the main
tank". <Mmm... I would not> He said if I am worried about my
Hermits and Liverock with the countless, exciting hitchhikers,
including Mushrooms and other Coral Polyps, then try Kick-Ich or
Rid-Ich or whatever was "organic" and nonlethal to Inverts...
Said it works "occasionally". <This is an honest
statement... Also kills, results in the loss of everything on more
frequent occasions> I said that independent research has been less
than favorable... He said to just use CopperSafe. I referenced Hospital
Tanks and Fallowing and Quarantine and FW Dips... I might as well have
said that the "Internet" told me to dunk 'em in diesel
fuel... Says I'm really over-thinking this. Am I? <Assuredly
not> I guess that's an easy mentality when, as a retailer
dealing in high volume, you have two systems: FO that you can Copper...
Or, Reef tanks with inverts... If there so happens to be an infested
Clown or Tang you simply don't treat it... It will either live or
it won't. Instead, last night, I sterilized my 10G, <Mmm, need
more room/volume than this> pulled out the old Penguin HOT and got
ready to go fishin'. After work I swung by LFS and filled my jugs
with 15G of RO/DI saltwater... Said I'll take the CopperSafe! Even
bought a new Heater, too (told him not to ask what I was doing). Ran
out of OSH with a bunch of different size PVC pipes and elbows (am now
broke)... Came in prepared for a long night... Turned on the light...
Not a speck anywhere on anyone. If I had Crypt, would they not be
multiplying? <If a single/starting infestation... could be just
moving into the next phase... off the fish hosts> Really? If I truly
introduced it as a result of failing to Quarantine, and it was now
visible on my fishes... Where did they go? <See Crypt's life
cycle... on the Net, WWM...> I think I have frickin' air bubbles
and sand... Should I really de-aquascape my entire display and put all
my fish in a... ahem... 10G tank? <I would not... at this junction.
IF your fishes are in apparent good health currently, I'd wait, be
observant for now... As you state, you/no one needs
"options", but really to sort through and set upon one
definite path... For me, for now, given what you have related so well,
I'd be patient. There is much more (currently) to be lost than
gained by over-reacting. SHOULD a protozoan complaint manifest itself
in the next few days... I would STILL not be so fast in moving the
fishes... It may be better for you to aim/shoot for a sort of stasis
here... Did I reference this last time? Here:
http://wetwebmedia.com/parasittksfaqs.htm and the linked files in the
series above...> For a minimum of 4 weeks? Or a big Rubbermaid piece
of Tupperware that my Girlfriend does not at all want to look at in our
one-bedroom apartment? I put a lot of work into this! Where, pray tell,
are my parasites? <Perhaps non-existent, maybe onto an off-host
reproductive process> Would you Fallow or not? <Mmm, what was
that statement/response that Dr. Frank Aubrey (SDSU) uttered years ago
during a "Creation vs. Evolution" debate, when asked whether
he truly believed that humans were derived from apes? "Not
yet."> And really... How long at 80-82 will it take for Crypt
to cycle and die? <Mmm, most of it in a few weeks... some maybe not
for a few months...> I have to go to Hawaii in mid-January...
(Nightmare!) <Heee!> Should I just be happy that I now have a
future Quarantine Tank? <I would be> That's simple and
somewhat reassuring. Here is where I find some inconsistency in the
advice: If I were to set up a Hospital Tank... Would I take nice
PH/Temp/Cycled water from Display Tank to fill it? <Initially,
yes... this is generally best... Unless you have another/parallel
system that is established that is pathogen free> Whatever
Pathogens/Parasites will be transferred to Hospital, but killed fairly
quickly with the Copper, right? <Yes> I'm guessing that I
would have to do something along the lines of 40-50% water changes
every other day or so? <Maybe... need to test... usually for
ammonia...> That's fine... But from where do I get the water?
Main tank? <Mmm, no... from new water made up that is lacking
parasites> It wouldn't shock the fishes. Copper will keep on
killing when I re-up for water change, right? <That's the
theory> Oh my god... I know this is posted, but it goes a few
different ways from here. And I don't have much money. Do I tell my
girlfriend that I'm getting her a RO/DI unit for Xmas? <A very
thoughtful gift in my estimation> Our love is like a Deep Sand Bead
that, by the way, I need to increase slightly? <Yes, and stir
gently...> I am going crazy. I feel like we're going to end up
on a sofa with a bucket of fishes between us and the therapist. I wish
I could sit back and enjoy the fishes that I assume are swimming on the
other side of that wall of Diatoms... Ain't we a wishin' bunch?

Cloudy fins, SW fish diag.
5/30/08 Hi, I have a Longnose Butterfly that is covered in a fine
"dust". It covers his fins and makes them look cloudy.
<Err... such cloudiness is often symptomatic of Amyloodinium, aka
Velvet... very bad> It also covers the front of his body and
recently five or six spots turned up on each eye. Initially I thought
they were air bubbles because they didn't always seem to be in the
same spots and he eats really well, doesn't scratch against rocks,
and is not shy. He has been developing the spots for about a month now
<Oh! Then this is something else. Velvet would have killed all your
fishes w/in hours to days> and I have hesitated to treat him for
fear of killing him with the treatment when I wasn't sure he was
sick. <You are wise here... Perhaps the root cause is
environmental... not pathogenic> When the spots turned up on his
eyes and didn't go away after I turned off my skimmer I decided
they weren't air bubbles and he must have something. I removed him
from my main tank, gave him a freshwater dip with Methylene blue and
put him in a quarantine. The spots are very small and I can't tell
what color they are except to say they aren't white. My water
quality is good (0 ammonia, 15 ppm Nitrates) and everything is
consistent in my tank except sometimes the fish only get fed once a
day. No other fish show signs of illness. Do you think this is a
parasite? fungus? <I do think this Forcipiger may be infested with
subcutaneous worms of some sort or perhaps Sporozoans...> Should I
treat with copper? dips? <Mmm, none of these> When treating with
copper should I remove my bio wheel from the quarantine tank and put it
in the sump of my main tank to avoid killing off the good bacteria
during treatment? Thanks, Brendon <I would first try a vermifuge...
See WWM re: http://wetwebmedia.com/vermifugefaqs.htm and in series

Shrimp goby pair quarantine... Actually, Disease, part. Protozoan
ID, trtmt. 8/17/08 Hello to all and thank you for being
able to ask questions, <I as well> it is greatly appreciated. I
am in need of some guidance and direction as to what is the best way to
address my current situation. My tank came down with what I now believe
was Brooklynella. <Mmmm, not likely> In one day I thought I lost
all fish. <Then no> Symptoms were cloudy eyes, peeling skin and 2
dead fish clown and pseudo. I also had a yellow watchman goby pistol
shrimp pair which I had assumed perished as well because I had not seen
them in a while. I was going to let the tank go fallow following
directions listed on your site. Then one day I put a very small amount
of frozen food in the tank and out comes the goby and shrimp looking
very healthy. So my question is now what do I do? <Likely
nothing> Im thinking of dismantling the tank to catch the goby and
shrimp and place them in a 10G quarantine tank. <... for what
reason/s?> Should I catch both or just the fish? If just the fish
will they still pair off later after reintroduction? Also what should I
use to treat the yellow watchman goby and how often since I see no
signs of disease on him? <I would do none of the above> I was
planning on using a sponge from my tank and also water from the main
tank into the quarantine, but would it be better to not use the water
from the main tank since the disease is in the water from the main
tank? I would really like to keep the goby paired up with the shrimp
but since I will most likely be medicating the fish I am unclear as to
what to do? If you recommend a dip and then placing in quarantine how
would I know if it worked since I don't see any signs of disease on
him and its been 10 days now since I lost the other 2 fish? Thanks

Help! Unidentifiable Disease on my fish!
System... 1/16/08 Hi There, I need your help and fast.
I have a 260 gal tank with a foxy face, Hawkfish, 2 dwarf colored
beauties, <Centropyge?> a saddle back clown, and 1 candy stripe
shrimp. My boyfriend have recently acquired this 7 year old happy tank
from his father. I had been doing lots of research in reef aquariums
and gladly took it off his hands. We have both a protein skimmer and
the "bio ball" type filters. 2 VHO fluorescent lights and 1
actinic.... I know we could stand more lighting we're purchasing
some metal halides in the upcoming month. Anyway about 4 days ago we
bought our first anemone a smaller rose BTA. I've read that all
fish and inverts are to be quarantined for a min of 3 weeks. I asked my
LFS before the purchase how long they isolate their fish / inverts, and
how long do the recommend for my new BTA. the girls said that they have
already iso'ed all their specimens before being brought out on the
floor. Then told me not to iso off the BTA b/c you should never do this
to any invert. This was the opposite from everything that I have
read....... I followed what she said and now I fear I'm paying the
price. The BTA seems happy eating well moved around a bit but seems to
have found Our foxy today (3 days later) seems to have a few black
spots on it ..... <Paravortex?> So I think ok it's black ich.
Only on the top on the fish and on some of the fins there are larger
white bumps ... at first I thought maybe this is some sort of parasite
that's latched on... pretty sure it's not bacterial. He also
seems to have a few scratches on both of his sides where I'm
guessing that he was trying to rub these little buggers off. I google
up black and white spots and foxy seems to have symptoms of both black
and white ich. I don't know if that is possible <Oh yes...
is> but it doesn't seem too unreasonable. I started to prepare
my fresh water for a dip <... but replacing the fish/es back in the
infested system?> and after the water heated up (about 2 hours or
so) I came back and all the larger white lumps are gone. The smaller
black dots are barely visible and now his tail fin is covered in a fine
mucusy substance. He's hiding in the rocks a bit more than usual
but is still eating fine not acting noticeably lethargic. I can't
find anything to match these symptoms online. What the heck is this and
how should I treat it? Remove the BTA to the hospital tank? Or only
Foxy? Laurel <... all the fishes need to be removed, treated
elsewhere... or a decision made to "weather" the infested
system... Please, when you have time, and soon... start reading here:

"Thing" on Firefish I just purchased a firefish on
Sunday, and yesterday, Monday, I noticed that he has something coming
out of a hole behind his pectoral fin. The hole is in his
"armpit" and there is not one on the other side. This thing
is a yellow-white curlicue that comes out, and looks like it goes back
into the hole it came out of. It is maybe 1/2 cm long. By curlicue I
mean kinda like wood shaving, or piece of sawdust. He is having no
problems swimming or eating. This thing doesn't seem to be
bothering him at all, but I would like to know what it is and if I can
do anything to make it go away. (The way it is shaped, I think it may
be a piece of intestine, maybe?) Thank you! <Mmm, my guess is that
this is an external parasite... a copepod likely (do put the terms
"copepod fish parasite" in Google and look at the
"images"... Can be excised with forceps likely... and careful
holding while in a net... Bob Fenner> Parasitic
Problem...Or??? Hi to you all, <Hey there! Scott F. here
today!> You all helped me out quite a bit when I first started my
tank 4 years ago. <Glad to hear that!> The tank has been pretty
good. Some wonderful successes and some sad failures, some fish jumping
out and some corals just not happy, many other fish I have had for
years and corals have been thriving for years. <All part of
the joy of the hobby.> Love learning all this. But now of course,
the problem. Got some new Clownfish, the others slept near the overflow
and Walla.... gone. Jumpers, the little dears. So now I have a cover
for the tank and two new clowns quarantined for 3 weeks, they looked
happy and fabulous. <Glad to hear about the use of
quarantine!> Put them in the display tank with a Sailfin Tang and
Yellow-tailed damsel and the corals and rock and all that. Next day
spots, but really small - like so small that we had to get the
magnifying glass to see them. <Hmm...potential problem...?>
Freaked out, scooped them out of the display tank and wrung my hands.
Next day not a spot anywhere. Next week still no spots (my husband sort
of accused me of ick phobia). <That's a good sign> Put them
back in the display tank, all is well. Two days later and Tang has
spots, but try as I might, I find it hard to say that they look like
salt. They are white and then some of them are sort of dark grey. He is
fine (they all seem well) and I begin reading about catching Tangs. I
have to wait for the weekend to catch them when I have the ability to
pump out the water in the tank and get them and put them all, and I
know ALL, into the quarantine tank. <Yep- If you suspect a parasitic
illness, "fallowing" the tank is really a smart idea, as it
will interrupt the life cycle of the causative protozoa...> Only
guess what? Nobody has any spots on them at all anymore. I have read
about the cycle and I get it, but when ick is swimming in the water and
searching for a host does it just go on one fish and leave all the
others? <Interesting though, but not too likely. The protozoa enter
a phase where they will attach to a suitable substrate for a period of
time before they emerge again...in potentially greater numbers.> Do
they all fall off again, at once, from the host fish and appear absent
from the tank? <Well, they will follow a definite life cycle.> I
tried to find some info on the web site with out bothering you guys but
alas the weekend approaches and although all the fish look absolutely
fine. I am wondering if I should give up the whole darn day to try to
get the fish out of the tank or can I wait and see if the spots come
back. <Hmm...tough call. I have become very conservative over the
years, and generally will move the fish when I have a good suspicion
that a parasitic illness is a possibility.> And is there anything
else that could be making spots that is not Ich or Velvet or a
parasite? <Hard to say. It is possible that there could be some kind
of trauma to the skin, but in all likelihood, you're looking at a
possible parasitic illness here. I'd operate under that
assumption.> Are you thinking to yourselves...that nut!!!??
<Nope- I hope that you're not thinking that about ME! LOL> I
hope not....Thank you once again for being here.. <Glad to be
here for you. Take a conservative approach, watch the fish carefully,
and be prepared to spring into action should it become necessary. Good
luck! Regards, Scott F.>
A " Lumpy" Griffiths Angel Hi <Hello> I have
a question for you, which I think I know the answer to......But I need
to ask. <Okay> In my store, I have many large reef display
tanks. One of these is a 400 Gallon, very well stocked
reef. I only have a few fish in there. a small
yellow tang, medium purple, a combfish, a fourline red sea wrasse, a
multicolour angel, medium Black Tang, and a
3.5" Griffiths. I love the Griffiths, and I got a few
with my last shipment from Hawaii. <Mmm, you mean
"through" Hawai'i... not found here> I chose one to
keep, isolated him for 2 weeks, then put him in the tank....everything
went well for a few days, but now he appears to be a bit lumpy....like
he has a dozen or so small bumps on each side of him....he eats
readily, and I feed Live Brine, and some Tetra marine pellets 3 times a
day, but in small quantities. In fact, he seems to be first
to the food. Question....what is it?, and if I soak a few
pellets for a moment in the "yellow-green" water....and
almost hand feed him......will these antibiotics kill my reef in such
small doses? <Not likely> I know you won't want to put this
on your site as it might encourage a lot of people to do the same, with
disastrous results. <We post all> My system has a 4 inch
DSB, 200kgs of quality Live rock, and a heavy duty H&S
skimmer, as well as a trickle filter and a little activated
carbon. I use natural sea water which I UV, skim
and O3 before lab testing and adding to the systems Normally I
wouldn't worry too much about the fish, as most seem to heal very
quickly in this tank, but I'm sort of attached to this
guy regards JD <I too like this genus of Angels... What yours is
exhibiting is very likely some sort of worm infestation... subdermal...
nematodes, maybe acanthocephalans... Not treatable, not likely
"too" debilitating, not catching. Bob Fenner>
Freshwater dip I just freshwater dipped my flame angel after
about five days of worsening cloudy-eye and fin rot... There were oval,
thin, opaque things in the dip water. I thought they were scales that
were knocked off at first, but do you think they could be flatworms or
something? <They could be scales but they might also be
flukes. You can use Praziquantel. It works great and only stays in the
water three to five days.> My fish was scratching himself for
a week or so... now in QT after the dip. If they are parasites, are
they contagious? <Yes they are very contagious.> How
to control them? Thanks guys. A second opinion is often all it takes to
keep us from being ignorant... <Good luck, MacL>
Do White "Hairs" Indicate a Parasite? 4/9/04
BACKGROUND - Friend broke down tank and gave me a 4" blue
tang - The tang has pale pits all over its head suggesting lateral line
disease, though the line looks fine <natural sunlight and improved
feeding will improve this> - Tail is frayed and oddly bumpy
near its base - These symptoms have remained constant for 6
months <hmmm... does not sound likely pathogenic for lasting
this long without getting better/worse> - Behavior completely
normal for a blue tang (healthy swimming, appetite, etc) - I have
provided no treatment - Goby and Banggai Cardinal tankmates
exhibit no signs of illness NEW SYMPTOM - I just noticed a
series of white "hairs" sticking out from his back, directly
below the dorsal fin. <odd> - These bristles are
parallel to each, angled from front to back (like hair blowing in the
wind), the thickness of thread, and number about 10.
QUESTIONS 1. What's wrong with this fish? <not sure
by the text description... a clear photo would help. Else do consult a
good manual like Untergasser's Handbook of Fish diseases
(TFH)> 2. What should I do to help him? <ID the
symptom first before any move or treatment. Get your Quarantine tank
ready if needed if its not still running> Thanks in advance
for any relevant info/advice. - David <I see that you
are form Boston... do check out the excellent local club: The Boston
Reefers. They have their own website (slips me now... do a keyword
search) and they have a forum on reefcentral.com They are also hosting
the national conference this year in September.. an event not to be
Moorish Idol Woes / Parasites (7/22/04) I was hoping you
could help me with a disease diagnosis and treatment. I recently
purchased a Moorish Idol 3 weeks ago. He has been eating everything I
give him and has been doing fine. <Ostensibly, anyway.> Until
today he has developed small "dusty'" white powdered
spots over his body. It does not look grainy or sandy like ich. <Ich
doesn't necessarily look that coarse. Velvet tends to be powdery,
perhaps this is it.> It looks like it is under his skin,
nearest his gills and eyes. He is still eating normally and swimming
around as normal, maybe a little faster than normal. There does not
seem to be any gasping or clamped fins. <Good signs all.> He is
the only tank member that looks like this. <I'd get him out of
there and into a hospital tank for treatment.> He also has developed
one cloudy eye. <May be bacterial infection.> It is slightly
enlarged and grayish in color. <Search "Popeye" on WWM for
info.> Have treated with Epsom salt but has not helped. All help is
welcome. Thanks <This certainly sounds parasitic. In your shoes,
I'd get him into a hospital tank for treatment. Read the parasite
articles/FAQs for options. Steve Allen.>
Amyloodiniumiasis or Brooklynellosis or
neither! Hi, I just finished reading this month's
issue of "Conscientious Aquarist" magazine. Awesome. One more
reason to surf the web at work! << I enjoy it as well. >>
I have a 72 gallon tank with 6 shrimp, 1 hermit crab,
1 Banggai cardinal, 1 Ocellaris Clown and 1 Orchid Dottyback -in that
pecking order! Almost everyday the Dottyback has a patch of mucous on
it's surface, body or fin, that is about 1mm by 1mm. << This
wouldn't worry me. >> It moves around day to day and even
morning to evening. All fish were quarantined -3 weeks for the cardinal
and about 2 weeks for the other two. Nothing showed up then. The
Dottyback has been in the display for over 6 weeks now and has been
showing these symptoms for the past 4 or 5 weeks. << If he swims
well, and eats, I say don't worry. >> This
isn't ich, as I've dealt with ich before when it wiped out
everything in my tank twice!!! Upon reading WWM, these symptoms appear
to be Amyloodiniumiasis or Brooklynellosis, except for the fact that
the fish is behaving fine and has been for over a month -knock on wood!
Could this just be damage from scraping against rocks and decor -he is
a pretty jittery fish! << Usually fish will scrape and rub
against rocks to rub things off of them. >> Tank had been set up
for 11 months now. The shrimp have been there since day one, crab since
December, cardinal since April, clown since mid-may and the dotty back
since 5/28. No additions since then. Salinity -1.025 Nitrates
-don't register on test kits... Ph -8.0 -slowly increasing it to
8.2 with Seachem Marine Buffer Temp -78.8F just before lights out to
78.1F early morning -consistent everyday. 20% water change 3 times a
month. Should I be concerned? Every time I move a fish to the hospital
tank for treatment I end up killing it, so that's my last option.
<< Well here is what I would do. I would buy a tank
raised cleaner goby, and maybe a cleaner shrimp. If it is a
parasite problem they can really help. I wouldn't go
with the hospital tank, unless you have to. As long as the
fish is out swimming and eating, I wouldn't be too worried.
>> Thank You! Narayan

Possible Parasitic Problem? Hi There, <Hey! Scott F. here
today!> I recently purchased a pair of clowns (well two days ago
actually) the one has adapted really well and is diving around the
place however the other looks very lethargic and is breathing
heavily. Tests all show OK. <I assume that means no
detectable ammonia, nitrite> I appreciate that other posts ask
similar questions however there is no slime on the fish nor white
spots. He hangs in his hosting coral all day and hasn't
fed on two occasion (but nor has the other clown.) Is this
really bad? <Well, it's hard to be sure. Sometimes, a fish can
have Amyloodinium ( a virulent parasitic disease) without the other
obvious external signs; just lethargy and difficulty in breathing.
I'd keep a careful eye on this fish, and be prepared to take
aggressive action if it becomes necessary. If you've eliminated the
possibility of environmental problems, focus on the possibility of
parasitic illness. Use the resources that we have here on WWM on
parasitic diseases, and feel free to ask questions again if we are able
to help you out. Good luck! Regards, Scott F.> Thanks in advance.
Chris I have a 40 gallon Chromis tank with an AquaMedic 2000 P/S, 2
powerheads. Tank is 10 weeks old; I have three shrimps, 10 snails, 10
hermit crabs, 1 lobster, and 35 lbs of live rock. The only fish are the
two clowns. Calcium 460, KH 8.3, nitrite, nitrate & ammonia 0,
salinity 1.026 temp 26.5 (in the day).
Bummed-Out By His Blenny!
Hi <Hello there! Scott F. with you today!> Great site. <Glad
that you enjoy it! We're thrilled to bring it to you each day!>
I have a 90 gallon reef with 90 lbs of LR. I have had a lawnmower
blenny in the tank for approximately 9 months. All parameter on the
tank are great a/n/n all 0. Everything in the tank is thriving except
my blenny. He eats all day mostly micro algae and will take a few bites
a day of what I throw in for the rest of the fish. By the end of the
day is stomach is nice and full. But come morning its completely
empty. I mean empty, sunken in. He seems to be slowly
deteriorating away?? <Not good...> I don't understand why??
Is there some type of a bacterial infection or something that could be
causing this?? <It is possible that an internal parasite of some
sort is at work here> Is this an indication of cyanide?? <Not in
my opinion...If it were cyanide, the fish would generally expire
shortly after eating its first few meals> Is cyanide collection
commonly used on these?? <Not to my knowledge> He grazes all day
on the micro algae so I'm pretty sure, theoretically he is getting
plenty of food. And, like I said by the end of the day he looks
slightly plump. <At least he is eating...A good thing!> This is
my favorite fish by far, and I don't want to lose him.............
Thank you for any help or suggestions. Matt <Well, Matt-
I'm going to operate on the assumption (gulp) that we are looking
at some form of internal parasite here. There are a number of
over-the-counter fish meds to address this. Sometimes, the cure is more
damaging than the illness, however. I'd search on some of the
e-tailers for a medicated antiparasitic food, and hope for the best.
Otherwise, maintain excellent water conditions and keep on top of
things in his tank. With a little TLC, he can pull through just fine.
Good luck! Regards, Scott F>
Are there parasites that you can see? <Oh yes... some
crustacean parasites of fishes and other aquatic animals are quite
large for example... some inches long> After close examination on my
aquarium I notices these extremely small moving creatures in the water,
some walking on the glass. Under a magnifying glass they almost look
like shrimp. Could these be harmful or might they just be something
that the fish stirred up in the sand? <Likely nothing to worry
about. Please read here re: http://www.wetwebmedia.com/pericaridanfaqs.htm
Mystery Parasite I've been reading over all the parasite
and disease FAQs on your wonderful site and others. I am
still confused on what my little domino might have had. Two
days ago I noticed two large white spots (1 was long and thin and the
other was larger than his actual dot and protruded a little) on my
domino damsel. I gave him a fresh water dip and that seemed
to revive him a little but things just got worse. He stopped
eating and moving around like normal. I couldn't get him
out of the tank either because he would move enough to hide from
me. I found him dead this morning with most of his coloring
wrong. I am not sure which parasite this is. I
don't think it is ich because there were only two large
dots. I am leaning towards velvet because the spots were
large. <Well, the fact that he displayed some raised areas on his
body, and did not mention that the fish displayed rapid breathing
(classic signs of Marine Velvet) and other signs of distress, I think
that it may be some sort of parasitic organism (trematode, etc.).
Velvet (Amyloodinium) also manifests itself as a very fine
"dusting" of spots (much smaller than you see in ich), and
kills rather quickly. Curious enough- yours died rather quickly...>
I plan on removing the rest of the rockwork out.. moving the
inhabitants into the qt and letting the tank sit for a
month. Should I wait till I see symptoms on my other damsels
before I use copper? <Whenever you're dealing with a potential
parasitic infection (especially if you even suspect Amyloodinium),
removing the fish and letting the tank run fallow is a conservative,
prudent move on your part. Better safe than sorry. I would hold off on
administering copper or other medications to the fish unless symptoms
manifest themselves. And, of course- NEVER treat the display with
medication. I think that you are on he right track here!> Thanks so
much for your great site. Alex Miller <Really glad that you enjoy
it! Sounds like you're learning a lot from this experience- keep up
the good work! Regards, Scott F>
Finding The Right Cure Hi guys, <Scott F. your guy
tonight!> I have read most everything you have on Gill Flukes.
I still need some help:-) <That's why we're here!>
My Percula had started breathing rapidly and scraping his gills
along the intake tube. The hippo tang is just a baby and he too
has been breathing rapidly and scratching as are the Firefish and
neon goby. :-( <Not a good sign...Could be flukes...could even
be Amyloodinium. Verify carefully!> I have a 30 gallon tank,
which has now become the QT tank. <Excellent to have> I
tested the water and then had LFS test against my test (water
great). I initially treated with copper thinking it was ick then
I noticed the breathing. <Well, copper may not be that
effective against flukes...there are many different views on that
one...> So I call my LFS and they sold me Fluke Tabs and told
me to Â½ the dose as this stuff is very strong.
<Haven't used it personally- but have heard the same!>
I still have sand and a few coral skeleton decorative pieces from
before I was planning to move everyone to my new 55 gallon reef.
Nobody has made it to the 55 as they broke out with this before
moving over. <Well, good that you were able to contain it>
I come home today treat with the first round of Fluke Tabs around
11:30 AM. I get back from doing 'stuff' to find my clown
still at the top (BTW, I have put a huge airstone, an air tube
and kept the filter on the back with no carbon to insure lots of
oxygen) and my hippo still breathing rapidly, his top fins going
a brownish color and he seems to be really struggling. These
(Percula and Hippo) two are my most worry as they are still
exhibiting all symptoms. <This really is starting to sound
like Amyloodinium...> 1. Am I expecting improvement too
quickly? <Depending on what you're dealing with, it could
take up to a week to 10 days to see improvement...Once you've
positively ID'd the disease or parasite, stay the course with
the treatment> 2. Is the sand absorbing the meds making them
ineffective? <Quite possibly...I always recommend treatment in
a tank without substrate, so that medication doesn't bind
with the substrate, reducing its effectiveness> 3. What is the
hippo's browning of the top fins about? <Hard to
say...could be as a result of the illness, or even damage caused
by copper> 4. My water temp is around 80 degrees because I
have read that when treating for sickness keep tank warmer???
<The thought is that higher temperatures speed up the life
cycle of parasites...> 5. How long do I treat them ? The Fluke
Tab box says two treatments should do it, then do a 50% wc after
three days of no symptoms? <Follow manufacturer's
instructions to the letter, with any medication....> 6. Should
I combine with freshwater dip or something? I already have copper
and quick cure in the tank along with Fluke Tabs. LFS said this
drug cocktail was safe. <I would tend to disagree...I
don't like to mix different medications....Maybe the
difficulty that the fish are experiencing is a result of this
mixture of meds, not disease symptoms, as I originally
surmised...Lots of possibilities> If you can answer any or all
these inquiries, I would be very grateful. Thanks. Christy Evans
<Well, Christy, my thinking is to very carefully ascertain
what it is that you're dealing with, then reduce your
medication to the one medication best suited for that condition.
Freshwater dips may be preferable to a medication
"cocktail"....Not a cure all, but a good supplement.
Hang in there...stay the course. Good luck! Regards, Scott F>
Finding The Right Cure...And The Right Disease! Hi
Scott, <Hey there again!> I think your diagnosis was more
accurate when you said that it sounded like Amyloodinium than
flukes. <I was afraid that it would...> We lost three fish
through what I believe was a misdiagnosis and medication
toxicity. I read up on Amyloodinium and it said that it lives in
the water more so than the fish. SO we have broken down our 30
gal HT, washed it and are currently reconstructing it. <Good
move on your part> We have fresh water dipped (ten min each)
all the survivors. Four fish total: 1 DSB Butterfly, two Firefish
(boy, their sturdy), and a neon Goby, and placed them into the
new 55 gallon reef that was ready before this broke out. <I
would have held them in the hospital tank for a while, but if
they seem to be healthy, we can accept that!> Should I find
that I have another outbreak of this what is the best method of
treatment (fish and tank). Now that we have a reef set-up the
stakes are higher when it comes to outbreaks. :) <The best
method, IMO, is to remove all fishes (even the seemingly healthy
ones) and place them in a hospital tank for treatment with a
commercial copper sulphate product, per manufacturer's
instructions. Meanwhile, the main tank will remain
"fallow", without fishes, for about a month...This will
help dramatically reduce the parasite population in the display
tank, and you won't need to use any medications in the
display...> We have also decided to wait two weeks or so
before replacing the ones we lost to insure the others are
thriving and eating and under no stress. <Don't forget a
full 3-4 week quarantine on every new fish...it's just gotta
be a mandatory part of your new fish "protocol"!>
Thoughts??? Thanks Again Christy Evans <I think that
you've got the basic idea...just remember to diagnose very
carefully before medicating in the future, treat in a separate
tank, and quarantine all new arrivals...That's the best that
you can do! Keep learning and growing in the hobby! Good luck!
Regards, Scott F> David W. Evans
One Fish, Two Fish...Or, Is That-"Two Fishes"?
(Obscure Trivia For Fish Nerds) Hi Scott, thanks for explanations! You
guys are awesome! <as always- it's so much fun to be of
assistance!> Some follow-ups down below: I'm still not sure if
my fish have Ich or Velvet... is there a simple way to distinguish the
two? What about the 'looks' of it? Both have white
dots? Same color? Size? Number? <Amyloodinium (Velvet) looks like a
fine "dusting" of whitish dots, as opposed to ich, which
displays salt-grain sized dots...Both appear whitish to clear in
color> As far as dosages of copper based medications (CopperSafe and
Cupramine) are concerned-that's what puzzles me... how can one be
1.5 -2.0ppm while the other same at0.5 ? Aren't they both chelated?
<Well, Coppersafe is chelated, and Cupramine is not...They are
formulated at different concentrations...> Which one do you like
better and is faster acting: CopperSafe of Cupramine (despite the price
difference)? <I've used both successfully. I find myself using
CopperSafe more often...Both are excellent products, IMO> Would you
adjust the temperature or drop the salinity along with the copper
treatment? <I suppose that you could raise the temperature a bit-
maybe to about 82 degrees F- as this might help speed up the life cycle
of the parasites a bit, but I'd keep oxygen levels high, with good
aeration. I would not manipulate the specific gravity, however- too
much added stress, IMO> Finally, my CopperSafe came with no
booklet... when I dose with 5ml/4gallons,what do I get: 1.5ppm? 2ppm?
Any idea? <Well, CopperSafe administered at the recommended dose of
one teaspoon to 4 gallons will yield a concentration of
1.5ppm-2.0ppm> Water Changes: I'm not planning on any water
changes during that time :-) Should I ? <I highly recommend regular
water changes- even in a treatment tank...Fish (even sick ones) still
give off metabolic waste, which must be dealt with. High water quality
is super important, particularly when you have fishes that may have
damaged gills, such as those infected with Amyloodinium or ich> I
included a cycled filter for biofiltration in the bare bottom tank and
I hope that neither CopperSafe or Cupramine will affect the
bio-filtration as the products claim. BTW, some people say that copper
will wipe out the bio filtration, yet both of the manufacturers state
that they are bio-filtration safe... puzzling... <Well, speaking
from personal experience- I can honestly state that I've never had
a problem with these products> Out of curiosity.. for instance, if
you have both Ich and Clownfish disease... I'm looking into it. I
suppose that formaldehyde (reducing agent?) could reduce the chelated
copper to its ionic form? <Hmm...I don't know the chemical
reactions that would take place for this to occur...and frankly- who
cares? (LOL!). Just don't mix these medications together...Use one
or the other!> BTW, is Clownfish disease only affecting clownfish or
other fish as well... <"Clownfish Disease" (Brooklynella),
is caused by a protozoan. It's usually associated with (imported)
clownfish, but can occur in other fishes, as well> And final, most
puzzling question... grammatically correct, plural from fish, is it
'fish' or 'fishes' ? So far I have
50/50 responses :-) <Well, I researched this for
you...here's the official "deal" on this issue:
"Fish" can mean a single individual, and can also describe a
group of individuals of the same species. When you are talking about a
number of individuals belonging to more than one species, the correct
term is "fishes". Example: "Dude, those Centropyge
hotumatua are expensive fish!"...or, "The coolest fishes are
pygmy angels"... Alright- enough of this grammar crap- my head is
gonna explode here!> Cheers, Luke <Yep- time for a drink, here!
Bottoms up- Scott F>
- Random Spots - <Good morning, JasonC here...> Dear
WWM Crew, am in need of your advice again. I have a 240
gallon with about 250 lbs. live rock, currently holds a 9"
Harlequin Tusk and 11" Golden Puffer. These
fish appear to be in extreme health, brilliant colors, they eat
extremely well, clear eyes, normal respiration. I am concerned because
they occasionally show small white spots on their pectoral and tail
fins, the spots come and go, the spots do not bother the fish, their is
no scratching or darting. <This isn't really abnormal and I have
made this same observation myself. What the spots are specifically is
hard to be certain - quite likely a protozoan similar to ich but not
ich. In any case, is mostly harmless - fish in good health show these
spots from time to time, but never seem affected by them or become
overwhelmed. If you didn't quarantine and/or dip these fish before
you put them in your tank, then they are the most likely source,
although it could have also ridden in on the live rock.> Before
these fish were added to the tank, the tank with the live rock was
empty for six weeks to insure optimum health of the tank before adding
my expensive prized animals. I would appreciate anything you
have to offer as I am concerned about adding any other fish to this
tank. I have a 12" Koran Angel in QT currently, and am
a little nervous about adding this beautiful fish. <Well, good plan
to have the quarantine going... I think as long as the angel is doing
well, and not a bundle of stress it will acclimate well to the new
tank. You may observe the same spots, but I doubt they will come to
anything serious. Do keep a watchful eye on things.> Sincerely
appreciate your time and your help. Thank
You, Jen Marshall <Cheers, J -- >
Striking Back At Disease! I have one butterfly left who is
laying upside down on the bottom breathing heaving. Yesterday the
smaller of the two had cloudy eyes and I found dead this morning. The
bigger one had a little bit of cloudiness but now doesn't look
good. I have been fighting Ick for about a week and a half. <Rapid
breathing and the cloudy appearance seem to be signs of Amyloodinium, a
far more virulent and fast-moving disease than ich. Hard to be 1005
certain from here-but may be the culprit. Check the FAQs on this
disease on the wetwebmedia.com site to confirm> I also have a clown
tang and a flame angel cleaner wrasse and shrimp. Do you think this is
the Ich that is getting them or something else? <As above- I think
it might be Amyloodinium...> Is there something I can do to save
this guy. Should I move him to quarantine and medicate with anything.
<Definitely should be moved to a hospital tank immediately and
treated with a copper sulphate preparation, per manufacturer's
instructions. Fortunately (bad term, I know), both Cryptocaryon (marine
ich) and Amyloodinium can be treated with copper sulphate. I really
think that you should move all of the fishes from this aquarium into
the hospital tank for observation and/or treatment as needed. Whatever
disease it is- it's in your main system, and radical steps must be
taken to eliminate it. I'd let the tank run without fishes for at
least a month, which will substantially reduce the parasite population
(it will likely "crash" for lack of fish hosts). Perform
regular tank maintenance (i.e.; water changes, etc) during this time.
After the "fallow" period, you can re-introduce your healthy
fish back into their tank. Although the parasite population cannot be
100% eliminated, you'll substantially reduce the population to a
level that healthy fishes should be able to resist> I have left them
in there tank because they all had the disease and was trying to use
kick ick to fix the and doesn't seem like it has done anything.
<Yep- I don't really have much nice to say about that stuff.
Treating the main aquarium is never a good idea, IMO. Just take
decisive action, observe your fishes closely-monitor the copper level
in the treatment tank with a reliable test kit, and stay on top of
things...With patience, you'll beat this disease! Hang in
there!> Thanks for your help. Thanks, Ian Roff <Good
luck, Ian. Let's hope that things turn out okay! Regards, Scott
I have a powder brown tang which has picked up a quarter of an
inch long light brown crustacean on its anal fin. The bug
looks kind of like a terrestrial rolly poly or pill bug. Also this
thing seems to be pinching the fin. I already have a cleaner
wrasse and shrimp. Do you know what this thing is and if and how I
should get rid of it? I bought your book this weekend and there
the bug was right on page 148. Also I have a white faced tang and
I now feel pretty bad about buying that cleaner wrasse. Anyway the
copepod disappeared after about 8 hours so I assume the cleaners
got it. I am glad I bought your book. It answered a lot of questions
and gave me a lot of ideas. Thanks for your time and Ill
investigate further before submitting a question. Everett West
>> Yes, this is a parasitic isopod... an aquatic type of rolly
poly... and it is best to remove it by catching the fish and prising it
off with a stout tweezers... Get ready and at the same time, daub a
little mercurochrome or Merthiolate on the remaining sore with a
"q-tip"... Bob Fenner
Disease/Parasite? Hi Bob, I was hoping you could diagnose a
disease or parasite. I have 2 large 300 Gallon Tanks and I recently
purchased a Hawaiian NASO tank for one of them. He is roughly 6 inches
in length and currently living in a 20 Gallon Quarantine Tank. Upon
entry into a Quarantine tank, I gave him a 10 minute freshwater,
Methylene Blue bath. 2 days later I noticed 5 small pimples about 1mm
in diameter located from his head, down to the base of his tail, along
the top part of the body. In the next 2 days, the pimple on his head
seemed to open up and a small white protrusion appeared to be coming
out of it. Additionally, the other 4 pimples seemed to be getting
bigger and heading towards the same direction. At this time, I noticed
the fish was darting around the tank so I took him out for a freshwater
formaldehyde bath. Since then, he's been acting much calmer. The
protrusion from the head disappeared right after bath, leaving a small
hole so I'm assuming that this is some type of parasitic
problem. <Mmm, maybe a parasite... if so, the most likely
"super group" involved is a type of worm... likely "not
catching" to your other livestock... would place this specimen
into one of your large tanks, just going through another pH adjusted
aerated freshwater dip en route> I can't figure out exactly what
he has from the various FAQs from your WetWebMedia (a great site
indeed!), so I was wondering if you had any ideas on cause and
treatment of this fish's problem. <No treatment advised>
Should I use copper? Or since these appear to be internal, would copper
be effective? <Not effective, you are correct, on internal
complaints> Also, aside from this problem, he appears healthy, so do
you believe him to be a threat to the rest of my stock in the display
tanks? <No, not a threat> The water quality in the main tanks is
far more stable and there is a cleaner shrimp to possibly assist in
helping the fishes immune system get a hold of the problem. <Yes, a
good idea.> Thanks in advance for your advise! Jeff

Possible parasitic problem Hi Bob. I have recently had
some issues with my tank. I have lost 2 Gramma loreto's in
the past year. The last one got some sort of parasitic infection
(dashing against rocks and obvious white spots; looked a lot like
Ich) and finally got to the point where I had to put him down. I
gave him 2 or 3 freshwater dips, and it appeared as though the
spots went away, but they came back very soon thereafter. I did
NOT quarantine him (not quite set up for that at this point; and
to make matters worse, I'll be going on a 2 week hiatus in
another 2 weeks - not sure if I have enough time to treat my
current fish and get him back in the main tank before we leave
(getting someone to fish-sit is one thing (HARD), but having them
attend to the needs of 2 tanks will be next to (if not)
impossible for us). <Hmm, the Royal Grammas the last couple of
years have not "come in" in any good condition,
'excepting the ones from Brazil...> Anyway, I picked up
another one yesterday, dipped him and he seemed to acclimate to
the tank rather well. Today, however, he is dashing on the rocks,
just as the other did. <Not a good sign... have heard various
theories on the species low acclimation, survival rates... poor
decompression, use of Quinaldine (real anesthetic, but still
enhanced mortality)...> I'm not sure what to think - all
my other fish look GREAT. Why would this disease pick on the
grammas? <Don't think this is a parasitic or infectious
disease... but some subsequent disorder from collection, handling
stress...> Anyway, if you have a down-and-dirty
suggestion (given the time problem) I'd really appreciate
hearing it. I am prepared to quarantine him in a 10 gallon tank
w/ an aqua clear mini and heater if need be. <Please take a
read through the marine index pieces on Acclimation, Quarantine,
Dips/Baths... stored on our site: Home Page ... may be some input
there of use, at least consolation.> Please advise. As always,
your feedback is appreciated. Oh, while we're at it, what do
you think about those trace mineral blocks? Even with 20% water
changes every month, my levels get low (calcium, KH).
<They're definitely better than nothing... and way often
less toxic than the Kalkwasser route so many folks fall into... I
have used them, and we make our own sorts of "delivery
mechanisms" out of similar materials for our use (a small,
non-commercial coral farm here> TIA, Bruce >> <Be
chatting my friend, Bob Fenner>
Re: Possible parasitic problem Bob, Went to the web
site, didn't see much on acclimation that applied (Methylene
blue in high concentrations (a squirt versus a few drops) has
been my weapon of choice...). <Mine too... and a worry/bother
that the materials aren't more intuitively accessible.>
The Gramma definitely has external parasites of some sort (spots
on the forehead, as did my last fish). He is still dashing and I
am wondering if a dip/copper treatment would be in order.
<Would hold off, lest you can really determine that this is a
parasitic problem... the/a treatment might well be worse than the
current problem.> The last Gramma I had was in my tank for
about 6 months before he developed these symptoms. It was not
immediate so I don't think your hypothesis about stocking
stresses would apply. <Sounds more like an "environmental
disease..." would look to your supplementation,
foods/feeding/nutrition practices.... and try the default (for
me) practice of vigorous live rock culture... maybe even some
starting material from the tropical west Atlantic...> This is
really starting to bum me out... Your thoughts? Maybe some
parasite that hangs out in the rocks? (I'm reaching here...)
???? Bruce >> <Don't reach, unless it's for a
microscope and some help locally by someone who knows
more/different about such matters... Do you have exposure to
such? Bob Fenner>

<Sounds more like an "environmental disease..."
would look to your supplementation, foods/feeding/nutrition
practices.... I have recently began using Combi-San (about
the same time this all started too, maybe?) and Selcon. I've
cut back on them both because of algae problems (the long green
stringy stuff), although I DO still use them. Also Phytoplankton
(Kent) for the inverts. Cut back on that, too (again, algae).
Food is NORMALLY OSI marine flakes. Sometimes brine, rinsed and
soaked in fresh water for at least 5-10 minutes. This 2-3 times
per month (I find my star corals need to be fed with target
feedings of brine...). Occasionally frozen foods (formula one). I
figure I have at LEAST 100 lbs of rock in my 85. I also have
(BTW) a sump with 24X7 lighting with some Caulerpa (no room in
the cabinet/power strips for a timer... Still working on it). PH
is about 8.3, haven't checked the salinity in a while, but
last I checked it was 1.024. Hard to keep constant with all the
evaporation brought on by my cooling methods.... Calcium/others
are lower than I would like, but still (what I would believe to
be, at least) acceptable. Not really any that I can trust farther
than I could throw them, no. And now?... I think I'm gonna
make an effort to prepare the quarantine tank tonight, maybe
catch him tomorrow night and isolate him so I can keep a better
eye on him. Any other thoughts? And, oh, thanks for the prompt
replies. Very nice when time is an issue... Bruce >> <If
you can catch the specimen, would take care to provide shelter
(even pvc parts) in quarantine... and look for Grammas out of
Brazil for now... Bob Fenner>
Re: Possible parasitic problem I will go with the
quarantine route, hopefully he will be in the tank tomorrow
night. So you think I should try some treatment method for him?
It sounds as if you really aren't too fond of copper, so how
would you suggest I proceed? Thanks. >> <Am actually a
HUGE fan of copper... pls just take a look at the med. parts of
our site... but Grammas, esp. ones in trouble already are easily
pushed over the edge with stock Cu++ treatments... would do a
smear prep. and look under a scope ahead of any dosing.... in the
meanwhile utilize environmental manipulation (lowered spg.,
elevated temp.) to do about as much good as can be done. Bob
Re: Possible parasitic problem Call it denial, but this
evening the lesions are almost invisible. I suspect that
they were trauma from being nipped by the other fish. <Ah, as
I suspect/ed... not really an infectious or parasitic disease,
but something environmental...> I had understood that
CopperSafe was CuSO4 and required an ionic (free) Cu test
kit. <Hmm, perhaps my memory is even faultier than I remember
(!), but isn't copper sulfate in CopperSafe a chelated
product? Is this the Aq. Systems product? Is it just pentahydrate
and citric acid?> The level of 0.15 was the level at which my
previous fish died...so I am pretty skittish about the
accuracy of the test kit. <Don't blame you.> I have a
microscope and slides (I am a Family Practice physician). I'm
not quite sure what the procedure would be. Do I net the
fish and do a skin scraping with the edge of the slide? If
so, would you expect to capture the parasite? For the
future, are there any good references for fish microbiology?
<Yes, and yes. Edward J. Noga, Fish Disease, Diagnosis and
Treatment. 1996. Mosby, the world.> I would risk moving them
if you think that this is water condition caused. But I
would hate to introduce a lethal infection into the tank. There
are other fish there, I just meant that the water quality
was sufficient to support the invertebrates. thanks >>
<It is indeed a toss up... and you can get a fuller grasp of
what is being "in the balance" of consideration in my
"Three Factors... " piece stored on our site: Home Page
though I suspect such a detailing of initial states of health,
suitability of the env., and presence/pathogenicity of disease
causing org.s will be "old hat" to you. Bob
PARASITE? Robert, I was told you could help me in
trying to diagnosis what type of parasite my fish has. I have a clown
trigger that has a brown line that goes from his body (near his top
fin) and extends through the top fin. The unusual thing is that there
is a brown or tan ball like thing at the end of it. I don't see any
specific parasite that I can identify. Just looks like something is
running up his top fin with a ball on the end. Do you what
parasite/what that might be? Also about 2 weeks ago when I first
noticed the thing on his fin, he also had a cloudy eye. The cloudy eye
has cleared up, but still has the thing on his fin. He also seems a
little sluggish and doesn't maneuver in the tank as good. Something
he seems to bump into the coral. He is eating good, and the first two
days of his cloudy eye he spent most of the time hiding. Thank-you,
Rick <Actually, along with the collateral damage you mention, this
sounds more like an "environmental disease", specifically a
trauma, rather than a biological/parasitic problem... Knowing how tough
this species is (almost always), I would simply try to keep the system
optimized and the specimen feeding... Though this could (unlikely)
prove to be some sort of crustacean or worm type parasite, you can
easily address this down the line... i.e. it should not become overly
deleterious as long as the host (your trigger) stays in good shape...
Do take a closer look at your system and water chemistry, husbandry
protocols... something slipped if this fish had a cloudy eye... maybe
just a "bump in the dark", maybe something more insidious.
Ich or Something like it? Bob, This is kind of long. I am so
sorry to bother you. <Not a bother. Take your time> I have
been reading your site and can't find a problem that is similar to
ours. We have a healthy (for the most part or else this email
wouldn't be necessary) 75 gallon tank. In our tank we have had a
dog-faced puffer for a month now. From day one he has had little white
spots on his fins and then they clear up and then the spots look like
they are gone and then he has on his body sort of like what a wart
would look like on a human in a clump together. <Might actually be
viral, viral mediated as well.> Sometimes the white spots are on his
eyes and he will close the eye or I will see him trying to scratch
himself on the sand or live rock. We have done the RO dips and some
days he looks great and some days he just looks terrible! No filmy look
to him at all. My heart feels for him. He still eats GOOD, and gets
around. Some days he rest a little more than others. But for the most
part, our little guy gets around. He also sleeps in the very same cubby
hole every time he rests. Do we need to vacuum out his little nest he
has? <No> What is this exactly (these little clumps that
look like warts on the body and the white spots on the fins)?
<Likely either some sort of protozoan or fluke (trematode)
infestation> We have other fish in the tank (lionfish, Huma Huma,
wrasse, and eel) none of them appear to have anything. Occasionally the
trigger gets white spots on its fins, but is not bothered by it and it
goes away the next day. Nothing spreads. We have had this tank set up
and complete for five months. Please help. We bought a UV Sterilizer
and it should be here in the next couple of days. What do you think
about that? Sorry this has been so long. <The UV will help
indirectly... and, see below> Thank you for your help. Lord knows we
need it! Angie <I would try "boosting" this animals immune
system by adding a liquid vitamin and iodide preparation to its food
(ten, fifteen minutes ahead of feeding), AND add the same prep.
directly to the water once a week, AND sneak in either bits of garlic
or one of the prep.s into its foods as well... AND lower the specific
gravity of this system down to about 1.017 for a month. All of this
should conspire to "tip the scales of health/resistance" in
your Puffer (and other fishes) favor. Bob Fenner>
Ick? Parasites? No idea... Hi Bob--- <Howdy> I have a
55 gallon saltwater aquarium with a clown trigger (immature),
Heniochus, flame fish, green wrasse, and four damsels (plus a starfish
and sea urchin). Everyone peacefully coexists <For now...> , but
in the last three days I've noticed very small white spots on both
the trigger and the Heniochus. I've seen no scratching, no change
in swimming or eating habits, no signs of distress from either. I did a
very brief freshwater bath for the trigger (maybe 10-15 seconds...it
showed signs of distress almost immediately) which seemed to help a
bit, but am concerned since there is still some sign of the spots (they
seem to come and go). The spots are probably smaller than a very sharp
pencil point and are not significantly raised. <Maybe ich, velvet...
perhaps nothing but "stress"> I am running two outside
filters as well as an undergravel filter, keep a UV sterilizer running
constantly, and occasionally use a protein skimmer. I do regular water
changes, and keep a close check on nitrates, etc. Am I better off
quarantining the trigger and the Heniochus and treating with copper
meds, or am I better off purchasing a cleaner shrimp or two and waiting
to see signs of scratching or obvious distress from the affected fish?
<The shrimp would likely get eaten. I might try a Gobiosoma Goby:
http://wetwebmedia.com/clnrfaqs.htm> This is the first real problem
I've encountered since starting my tank about 8 months ago, and
would very much appreciate your input. Thank you in advance for your
help, and thank you for a wonderful and informative website. <Thank
you my friend. Do keep an eye on your livestock, consider beginning
environmental manipulation if the cleaner goby doesn't stop the
recurring spots. Bob Fenner> All good wishes, Daryl Klopp
Possible ich break out? Hey Bob, Always enjoy reading your
website. Got a question for you, I noticed today that there was a small
white spot on the dorsal fin of one of my false perculas. It looked
almost like a tiny piece of bread crumb, there was a also a similar
spot on his right gill side. These spots are fairly tiny, maybe the
size of a pencil point or so, but should I immediately remove the fish?
Or give him a few days to see if he gets worse. <Hmm, need more
info. to give a more substantive response... How long have you had this
specimen, what else is in with it, do you have any purposeful cleaner
organisms?> He has exhibited no signs of stress and is swimming
well, eating... I have for perculas, two fire gobies, a striped damsel,
and a cleaner shrimp in the tank (55 gallons). <Ah, here we go.>
I have two big powerheads and a prism protein skimmer rated for a 90
gallon tank. All of the other fish seem fine. The only thing I can
think of is we had bit a cold snap out here and the temperature dropped
about 4 degrees. Is this enough to cause an infection or Ich? Water
quality looks good, but I have yet to test PH. <Maybe. I would leave
this fish for now... maybe start the environmental changes listed here
that others have tried: http://wetwebmedia.com/marparasitcurefaqs.htm
