RE: Blue Linckia and Water Changes – 05/06/08
Hi Eric,
<<Hey Cameron>>
Thanks for getting back to me so quickly - much appreciated!
<<My pleasure>>
Sounds like the situation for the blue linckia is grim.
<<Its “chances” are indeed slim>>
I can add more live rock and I will upgrade to a new filter system.
<<Likely only delaying the inevitable my friend>>
The tank is stocked with a blue tang, yellow tang, lipstick tang
<<Yikes! Only the Yellow Tang is really suitable to your 75g tank…the other two Tangs need larger quarters>>
, red hawkfish, dottyback, yellow goby and 2x maroon clowns. They are all well established in the tank with the newest member (the tiny yellow goby) having been introduced about 12 months ago. My tank is an Aqua One complete unit. One of my concerns is that it is quite tall (70cm or 28inches), which I understand affects the oxygen level and I added an internal power head to try to improve this by increasing circulation.
<<Mmm, yes…the taller tank (as opposed to longer or wider) means a decreased surface area which effects gas exchange…but adding/increasing water flow as you have done will help with this>>
The tank has a built-in spay bar filter (98cm or 39inches long) in the hood and an external canister filter (Aqua One CF1200). I'd like to replace the canister filter and would be interested in your thoughts. I tend to balk at customized systems and want to keep it simple and compact. Do you think an Eheim Wet/Dry 2227 filter is suitable for my system?
<<Not really…not for a reef system. These filters are very efficient at processing Nitrogenous waste, but can’t metabolize it down to Nitrogen gas the way live rock/sand can. As such, they can easily overwhelm the processing capacity of the rock resulting in greatly elevated Nitrate levels…not as much of a concern in a FO or FOWLR system (where a wet/dry is best utilized), but can be problematic to a reef system. I think your canister filter is of better use, but not for filtering particulates. Use the canister filter for chemical filtration (carbon and/or Poly-Filter)…rinsing the media weekly and exchanging it monthly. Also, reducing your fish load (by two Tangs worth [grin]) would be of benefit>>
Thanks again for your help!
<<Hope I have!>>
Regards,
Cameron
<<Cheers, EricR>>

R2: Blue Linckia and Water Changes – 05/07/08
Thanks Eric, there is nowhere else that we can get this sort of advice and you've probably just saved me quite a bit of money!
<<You’re quite welcome, Cameron. Eric Russell>>

Re: got prob again, GF, NNS....
hello
dear Neale, you told me that fin rot may due to bad water quality but now this time water was perfect, so what do you think about the reason?
<Perhaps perfect now, but maybe not in the past? Provided the water is good now, give medicine to the fish, and you should be OK.>
and Neale I have 25 gallon tank if I use salt than the proportion would be 1 table spoon per gallon ?
<No idea; weigh the salt using kitchen scales. Six grams of salt is a level teaspoonful, so if you must "measure" salt, use that measurement. So a dose of 3 g per litre would be one level teaspoon per 2 litres. This assumes "normal" teaspoons!>
and what do you mean by (don't bank the salt on it) ? .....
<Doesn't work reliably.>
how many days I cant change the water?
<Do regular water changes (25-50% per week) adding the right amount of salt to each new bucket of water.>
after that should I change the complete water or half ? or should I give bath in salt water?
<Keep the salt in the water until the fish is healthy. Take care not to overdose! Do not add salt directly to the aquarium, but ONLY to each new bucket of water added.>
thank you Neale
ALI
<Cheers, Neale.>


Birth of baby shrimps
Hi,
My daughter is 7 years old and she is curious to know how are baby shrimps born.
<Many different ways. Depends on the shrimps. Is this a school project or simply out of curiosity. If the former, that's not something we're here to help with. If the latter, the short answer is this: most shrimps produce eggs that float away in the plankton. After a while the eggs hatch and the "baby" shrimps pass through a series of larval stages until they become miniature shrimps that settle down onto the substrate. Although the details are different, the basic idea of a larval versus adult form is similar to the way larval butterflies (caterpillars) are different to the adults. Some shrimps, mostly freshwater ones, do not do this. The mother carries a few large eggs under her swimmerets and protects them. When they hatch, the newborn shrimps are perfect miniatures of the adults, and immediately walk about the bottom just like their parents. If you get some Cherry Shrimps from a pet store, they breed easily if kept well, and you can watch this at home.>
Can you provide us the answer with pictures or video clip attached?
<No.>
Thanks,
Esther
<Cheers, Neale.>


Re: Platy Water Hardness
Very fun, I'm excited about this tank; I've never had freshwater shrimp before. I was thinking of Java Fern and Java Moss, but I could skip the moss and let the algae grow instead.
<Indeed you could. But the Moss is great for the shrimps. It gets clogged with food and algae, and the Shrimps spend all day out and about, picking away at it like an "all you can eat" buffet.>
I need to find either small pieces of driftwood or rocks but the LFS around me have huge gigantic ones that are really too large for a tank my size (20 gallon long).
<Feel free to use plastic, ceramic alternatives. Once the algae/Moss covers it, it looks great.>
Would putting crush coral in the filter be a good idea or looking for a certain rock to help keep the water "hard"?
<If you have soft water, then yes, adding a little crushed coral would be a fine idea. Don't go wild, because you'll still need space for the biological filter media (sponges or whatever). But a 50/50 mix of relatively small pieces of crushed coral and biological media would be perfect.>
I just looked up Lamia nigrofasciata and they look really nice!
<Indeed they are. Quirky yet pretty. Also look up Heterandria Formosa (Dwarf Mosquito fish) and Micropoecilia picta (Swamp Guppy) -- both tiny, peaceful and very cute livebearers. Add a few Nerite snails, and you have something every bit as fun to watch as a reef tank, but at a fraction of the cost!>
Cheers,
Michelle
<Cheers, Neale.>


Re: Troubled Mollie
Hello!
I just want to thank you again for your all of your help. Unfortunately Moe didn't make it :( I was really bummed.
<Ah, too bad. Sorry to hear this.>
I wish I would have known about your website before putting them in a freshwater aquarium. His companion, Flo, is doing great. She loves her new tank, and seems to be so much happier.
<Great! Mollies are just so much happier in slightly salty water, that you'll wonder why anyone keeps them otherwise.>
Because of space issues, I had to go with a 16 gallon tank.
<If you can, make sure the water movement is pretty vigorous. If they have to swim a little harder than otherwise, the tank will "feel" bigger. Kind of like a treadmill.>
I would like to add some tank mates for Flo, but I want to make sure that they will mesh well. You mentioned that the bumblebee goby does well in brackish conditions, is a 16 gallon tank too small for them?
<Should be fine. Awkward to feed because they must have live or wet frozen foods (like bloodworms) but otherwise lovely. Also look out for Chlamydogobius eremius, Rhinogobius duospilus, and Redigobius balteatus -- all small gobies of similar temperament and size that would work fine in a slightly brackish aquarium. Other options would be Rice fish (Oryzias latipes), Florida Flag fish (Jordanella floridae) and Wrestling Halfbeaks (Dermogenys pusilla). All good fish for small tanks.>
I have read that they are territorial and should I say "grumpy"..... is this true?
<Yes, but all they need is a cave (e.g., a seashell) plus about a gallon or two of space per specimen.>
Should I just stick with live bearers?
<If you want to. My current favourite is Lamia nigrofasciata, a funky little livebearer that's suddenly become quite common in England. It's very hardy, easy to breed, and tolerant of both fresh and brackish water.>
Thanks Again,
Lauren :)
<Cheers, Neale.>


Hi Rich, here's an update on my phosphate problem:
<Hello, and sorry for the delayed response!>
I received a TDS meter yesterday and measured the following:
tap water: 49
RODI water: 5
(btw, stupid question: can I measure the salty tank water? the TDS gave an error message when I tried?)<Yes, but the reading will be higher than the tester reads.>
Is 5 good enough? How can I get it to zero? My RODI unit (Water General) is pretty new and it was said that the filters last for a year (given that I only have a 40BR)..<You will need to add another DI cartridge to your unit or change the DI resins to new ones in your existing unit.>
Btw, had started to increase the B-Ionic dosage a bit and now alkalinity is still 3, PH was closer to 8.4 and calcium 450. Looks like PH and calcium is pretty much at the upper level, whilst it seems to be difficult to increase alkalinity (btw, I have also used the same dosage for alkalinity and calcium, as that'd what the B-Ionic instructions say; would it make sense to increase alkalinity and reduce calcium to try to get alkalinity closer to 4?)<You can skip a few doses of the Calcium additive and add only the alkalinity additive until things balance out and then go back to dosing both.>
I also got the phosban reactor and will install it this week-end and will be getting some more turbo snails. Hopefully this will get rid of phosphates/hairy algae completely (it seems a bit better already)...What do you think?<This is a good sign, but get the TDS to 0ppm as a priority and I would change the PO4 resin by now and add new. I would change it once every 2 weeks for the first 2 months and then change it once a month after that. You will see a better performance out of the product that way as it is stripping the nutrients from the tank faster.>
Thanks, Sam--
<HTH, Rich>

CMA2 on Amazon!
Hi Bob,
<Darren>
I think I may have helped to get the ball rolling about a year ago when I asked in a post script if you had any plans to write a second edition of The Conscientious Marine Aquarist. I hope it was a worthwhile endeavor for you, and I am looking forward to reading it. I just pre-ordered it on Amazon. It
says that it is due out in July. Maybe some day I can get you to sign it!
<Will gladly do so. Wonder why all this takes so long... James Lawrence/Microcosm sent me a copy a couple weeks back... Is VERY nice indeed. Cheers, BobF>
Take care,
Darren White

Tank Mates for Blue Spot Toby 5/6/08
<Hi Barbara, Pufferpunk here>
I have a blue-spot toby (puffer) in a 75 gallon tank. What tank mates would be good, if anything, for this fish? I would like to add porcupine puffer, if you think that they would be ok together.
<I do not suggest combining puffers of such large size differences together. In addition, an adult porc requires a minimum of 100g. How about a Valentini puffer? Also hardy, fast-moving fish like wrasses, damselfish & pretty much anything that does not grow too large or isn't too small, delicate or has flowing fins. ~PP>
Thanks, Barbara

RE: Aquarium Stand Leveling Mat – 05/06/08
Eric,
<<Hello (?)>>
Awesome, very good input.
<<I’m happy you are pleased>>
I believe a slight riser board to almost fit the tank would be a great idea. I would plan on putting the system in place, filling, allowing to settle, gauging any deviance and then taking it out and adding a shim across the areas, probably in front, to account for any deviation.
<<Indeed…and do think to add “long tapered shims” to provide support for the full span>>
It might also be able to be finished to look like a small base. Esthetics, you know.
<<Ah yes, I know very well mate [grin]. Tis important to keep the better-half happy with the tank>>
Shame, I thought the harder poly or rubber might allow settling to enough degree to take care of basic leveling by gravity :)
<Mmm…too much potential for disaster. Crack a tank and spill 75 gallons of water on the floor and THEN see how your wife feels about things!>>
Thanks so much!
<<Quite welcome. Eric Russell>>

Feeding Pholidichthys leucotaenia (The Convict Blenny) - 05/06/08
Eric,
<<Hello Petar>>
Please help me with http://www.wetwebmedia.com/pholodichthyidae.htm.
<<Ah yes, Pholidichthys leucotaenia…the Convict Blenny. I kept a trio of these in a reef tank when I was stationed in the UK…wonderful fish! (Hmm, perhaps it’s time for another trio…)>>
I got them very small with only one silver line in their back.
<<Indeed…their juvenile markings>>
How to feed them and with what type of food?
<<Though mine were a bit secretive, they were never shy about showing up for feedings. They will eat most any prepared foods (flake, pellets), and will also take frozen foods very well (mysis shrimp, fortified brine shrimp, blood worms)>>
I am supposing that this stripe will be split later?
<<Yes…as they mature their markings will become broken and will take on a more “striped” appearance. Eric Russell>>

Domino Damsel slowly declining, need more info 5/6/08
Hi Crew,
<Hello>
I need your help....my domino damsel is slowly declining in health and I am unsure on what to do next.
<Let’s try to figure it out.>
I have thoroughly checked all my levels...PH, Nitrite, Nitrate, Ammonia and Phosphate levels and they are all within acceptable levels. I am now doing this daily because my first fish I bought was the Domino and I do not want to lose him.
<Numbers please, acceptable is too subjective.>
All the other fish are fine so I cannot pin point any problems, the Domino is laying on the bottom of the tank for long periods and is very listless. It will occasionally swim around but looks disorientated, bump into something and fall back to the bottom of the tank.
He is not eaten now for a couple of days and obviously I feel as though time is running out.
<Not a good sign.>
I have found your site very informative and read many articles but I can find anything like this. He does not have any visible deformity to eyes or body, no lesions or visible cuts etc and I can not see any thing that would indicate a parasite or bacterial infection i.e. no change in colour, spotting or fin rotting etc.
I would really appreciate someone’s time and assistance, in advance thank you for your site and your help
Regards
Ian
<Need more information here. How big is the tank, how old is it, tankmates, water parameters, corals/anemones present to start with. In the mean time check out here to see if you get any ideas http://www.wetwebmedia.com/mardisindex.htm .>
<Chris>

RE: Domino Damsel slowly declining, need more info 5/6/08
Hi Crew,
<Hello>
First of all thank you so much for returning my email, it is so good to know someone out there is willing to help.
<We try.>
Sadly though my Domino Damsel died during the night, I blame myself for doing too little too late, my 3 year old son is a little distraught as this was our first purchase when we started the Marine Tank.
<Sorry to hear.>
Again thank you for your help, I will be monitoring the health of the remaining fish very closely and if there are any issues I feel a little safer now that the Wetwebmedia crew are out there.
With Regards
Ian
<Good luck.>
<Chris>


Re: Cyanobacteria 5/6/08
Scott V., Thanks again.
<Very welcome.>
I had mentioned that the Cyano was reforming, but I got home last night and there had been no real additional forming/spreading of it.
<A good sign, caught it early.>
I think that perhaps what I was seeing was the original Cyano that had been 'turned' by the vacuuming of the substrate, and perhaps vacuuming that substrate really well has removed a lot of the detritus and is slowing the Cyano quite a bit. Only time will tell.
<Yes, it will!>
As far as skimmers, I'm going to leave this one on here, and add an additional one.
<OK>
I can purchase a Prizm Pro for a good price brand new, this unit is rated for 300 gallons. Any thoughts on this model, being coupled with the Sea Clone 180 Gallon HOB model I have now?
<None I wish to share too openly :) I would honestly seek another model for this system, regardless of price. Scott V.>

Question about disease/illness in FW 5/6/08
Hello,
<Hi>
What is the most likely diagnosis for a fish that breathes rapidly and stays on the bottom of the tank. There are no physical signs on an illness on the fish's body. I have had this happen a few times and find it hard to diagnose and treat in quarantine. Both times it happened was when the fish was in my quarantine tank after purchase.
Thanks for your help.
Zach
<By far the most common cause of these symptoms is water quality issues.>

Neale Monks and Bob Fenner (Do you even have your own aquariums?)/question for my female guppy -05/07/08
An Evidently Unhappy "Customer"

Hello,
<Hello>
My question is specifically for Neale and Bob about whether they are even knowledgeable enough to be answering questions on this page.
<In a word, Yes.>
<<Please also see the profiles of these two fine men:
http://www.wetwebmedia.com/wwmadminsubwebindex/bobfresume.htm
http://www.wetwebmedia.com/WWMAdminSubWebIndex/wwmcrew.htm -SM>>
I have read a lot of what they have answered with and most of it is either mean, unknowledgeable, or them just saying read this. Well if they come to
you they want you to know the answer or at least have a decent idea.
<We all want answers, and 99% can be found with a simple search of the site, sometimes people need a little encouragement to help themselves, which is the best way to learn.>
So if you can prove that you really do know something other than read this or "Someone needs to read a book about Guppies. Males are aggressive. Guppies are NOT a good idea in tanks smaller than 20 gallons. This isn't up for discussion. If all you have is a 10 gallon tank, keep something else" or
Question about my tequila sunrise guppy - 4/12/08 this question where I know its because the swim bladder was injured. Wells that's all I wanted to know.
<Best I can offer is that if you don't like the advice find it somewhere else, there are many other resources available. If you need proof on their qualifications I suggest you read a few of their articles printed here and across the hobbyist’s literature and make your own decision.>
<Chris>

re: Neale Monks and Bob Fenner (Do you even have your own aquariums?)/ question for my female guppy -05/07/08
I understand what your saying but I'm not unhappy I am just wondering how they could even have a job like that if they can't answer simple questions.
<Apropos to what? Whilst I'm not that man to ask about reef tanks, I flatter myself I know a little about freshwater and brackish water aquaria.>
I also want to say that Chris is seems like your more knowledgeable than they are and I have a question.
<Chris is indeed a competent aquarist and a valuable member of the team.>
My female guppy ether has constipation, intestinal worms, or she is just going through the normal phases of birth?
<Difficult to say without a description of the symptoms or a photo. If you've been feeding the Guppy lots of algae and suitable live/frozen foods such as Daphnia and Brine Shrimp that have a laxative effect, then constipation is unlikely. Intestinal worms are not all that common, but if you see red threads protruding from the anus, then Camallanus is indeed the problem. Prazi Pro and other anti-helminthes drugs will need to be used. That said, most (inexperienced) aquarists who say they have "intestinal parasites" killing their fish actually have fish dying because of poor water quality or the wrong diet. "Intestinal parasites" seems to me to be another way of saying "this fish is dying, and I can't be bothered to figure out why, so I'm going to kill it and buy some more". Finally, pregnant Guppies don't normally behave any more differently than otherwise. They simply get very fat-looking, sometimes with the eyes of the baby fish being visible through the thin abdominal wall when birth is very near.>
The problem is I can't tell and she is laying at the bottom of my 5 gal birthing tank by herself.
<Sounds pretty bad really. Guppies don't normally sit on the bottom of the tank unless stressed in some way. So as every, do a pH test and a nitrite test -- almost all fish sickness ultimately comes down to poor water conditions. If those aren't issues, come back to us and we'll investigate further.>
What do you think I should do?
<See above. Cheers, Neale.>


re: Neale Monks and Bob Fenner (Do you even have your own aquariums?)/ question for my female guppy -05/07/08
When I tested my ph was lower than 6.2 and my ammo was read as non detectable.
<There is part of your problem, guppies prefer hard, alkaline water. To be honest this information is readily available in Neale's excellent article on guppies found here
http://www.wetwebmedia.com/FWSubWebIndex/guppies.htm .>
I didn't check the nitrate because I don't have a tester for it.
<Important to know, along with nitrites.>
I also notice the babies inside her move up and into her back in a way. Her tale also went from being fan like to close together. Food wise I feed her freeze dried blood worms, fish flakes, and veggie wafers because she's in with cherry shrimp, and snails.
<Ok>
The tank she is in is a 20 gal with a Whisper 30 filter and an air stone. I have java moss in the tank, some type of floating plant that I also have in my 70 gal, a purple tree like plant that I can never remember its name, and elodia. The only other fish in the tank with her was the male guppy.
<Keeping a 1:1 ratio of males to females can be rough on most female livebearers.>
The thing that concerned me the most was that the fry actually moved in her towards the front and upper side of her. Let me know if any of this help describe it and I can't get a picture because my camera is broke right now.
<I am guessing that the water quality is at least partly to blame for her problems. She may benefit from a very slightly brackish environment. Ultimately besides providing the optimum environment not much can be done to help her give birth. I do encourage you to read the previously listed article, much good information there. http://www.wetwebmedia.com/FWSubWebIndex/guppies.htm >

Comment -05/07/08
Hello, I was browsing your site for info and after reading through some of the faq I just want to point out that certain crew members are very rude to some of the people who submit questions.
<Oh?>
I just felt like commenting about it because I feel bad for the folks who have come to this site looking for help and answers and get a response pertaining to their poor English or failure to capitalize certain letters in their message without even receiving any info on the question they asked.
<If you look carefully, you'll see we rarely say anything negative about the quality of English from people for whom it is a second language. It's pretty easy for us to tell from the e-mail address or the sender's name if that might be the case. In which case, we'll make an effort to "fix" the e-mail before publishing it on the web site. Our gripe is typically with lazy native English speakers. Britons, Americans, Canadians... whoever. For these people, there's no excuse. Of course we don't care about the odd typo or abbreviation... what we don't like is sloppy English that demonstrates that the sender didn't read (or didn't care to observe) our House Rules. Let's be quite clear about this: these rules exist for a purpose, not bloody mindedness. Most of our visitors come to Wet Web Media via search engines like Google. They've decide to find out something about Black Mollies or Whitespot or whatever the heck they're having a problem with. Search engines are only as good as the quality of the English on the web page being indexed. If that page has good English, the search engine will index it effectively; if that page has poor English, then the search engine can't index it properly. Simple as that. So that's the deal: people who ask questions have to make their messages easy for us to put onto our web pages, and in return the sender gets replies from people at the very top of the hobby. Not 14 year old boys who've set up their first aquarium and happens to have a subscription to some two-bit online forum (no offence to 14 year old boys!) but from people who have kept fish for decades, write books about them, and contribute to every major English-language aquarium magazine on the planet. Is that really too much to ask? I think not.>
I mean, really why is it so important for someone to capitalize all the I's and insert the ' in can't.. Its not like you wouldn't be able to understand what the person is asking without them using the proper marks or capitalization.
<As said above, it's not really whether we can read the message, but whether other people can use those messages. If the message is opaque to a search engine or unclear to someone who doesn't have English as a first language, then that message is worthless to us.>
It just seems like newbies who ask questions here get treated differently because they might not submit their question properly or they might not know some certain basic information that more experienced hobbyists would know, but they are visiting this website to become more knowledgeable and some of the crew members are just a bit rude to them.
<On the contrary, there are plenty of "newbies" who routinely write back thanking us and telling us how things have improved with their hobby. Speaking as an Englishman, I understand that sometimes my directness comes across to Americans as a bit sharp. But then the flippancy of many Americans comes across as irresponsible to me. So we all put across impressions through our words that may not really reflect the real person behind the message. That said, I'm not sure everyone appreciates how much work goes on answering these messages each day. Many of us -- for no money -- devote hours each week to going through the mailboxes. Our dedication to the hobby is tangible in that sense, and we wouldn't be doing this if we didn't want to help. All we ask is that in return people make an effort to help us. Keep the messages clear and properly written. Avoid laziness. Don't write messages like "text" messages on a mobile telephone. Basically the "golden rule" -- do unto others and you'd have them do unto you. Thanks for writing, Neale.>

Re: red ear sliders -05/07/08
Hi Neale
Thanks for the information. How would I be able to tell between a slippery slimy deposit of fungus or and algae that is also slimy and slippery?
Thanks Christine
<Hello Christine. Simple: algae is typically greenish brown, but can run from reddish through to blue-green; fungus is off-white, perhaps grayish. Hope that helps, Neale.>


Sick fish in distilled water- yikes! -05/07/08
HELP!!! My fish is floating at the top of the tank. It is sideways so I can see it. Some scales are missing and it is hardly breathing.
<Sounds to be on the way out, to be honest.>
It looks normal apart from that but it is very skinny.
<Suggest starvation... have you been feeding it properly?>
I've put it in a separate tank with clean, distilled water.
<Distilled water will kill your fish. Remove. NOW!>
What is wrong with it and what do I do? Please help me save my fish.
<No idea. Need you to tell me what the fish is, how big the aquarium is, what the pH and nitrite measurements are. Describe the symptoms. Then we can do something (perhaps). Cheers, Neale.>

Do goldfish need less food when they are older than 1 year? -05/07/08
Dear WWMC,
You have a very informative site - thanks for all the effort that evidently goes into it. It's great to see such a wealth of experience about goldfish in particular.
<Thanks for the kind words.>
I have a query that I did not find an answer to on the site (though I did find a lot of interesting information): how do goldfish nutritional requirements change with age?
<Doesn't change dramatically, though yes, bigger fish eat less food relative to their body size than smaller fish. This is in fact true across the animal kingdom. While elephants eat a lot, in terms of percentage of body weight, that food is much much less than what a mouse eats.>
I have 3 fantail goldfish in a 30 gallon tank, along with a couple of Siamese algae eaters and some white cloud minnows. Everyone is peaceful and I never see the goldfish chasing the others, though they are now much larger. The tank is heavily planted, mainly with fast-growing, low-light things.
<Hope this tank is warmed somehow: Siamese Algae Eaters (Crossocheilus siamensis) is a tropical fish and needs water at 24-26 C, slightly more than Goldfish like. Not a combination I'd have recommended, though viable.>
The goldfish came to me when they were about 1 inch long, about 10 months ago. Two are now 3-4 inches and the third is more like 2-3 inches. The smallest seems to have a deformity in his mouth that stops him from opening it fully, so I think he gets less food than the others, but he is active and seems cheerful, so I leave him be, because I don't think there is anything I can do about his mouth anyway.
<Mouth deformities are common in Goldfish, and as you say, they seem to manage.>
My goldies get Hikari goldfish pellets and a variety of flake foods (different brands), they get some of the smaller pellets I put in for the white clouds (a community pellet mix), and they also have raw lettuce, duckweed, azolla (these they will eat until it's all gone) and the live plants in the tank. They love hygro, ambulia and similar plants, but they also seem to eat pretty much anything, including anubias, java fern, crypts and other things they are not
supposed to like much. One thing they are surprisingly not so keen on is elodea, so lots of that is growing in my tank at the moment.
<Perhaps less tasty than the rest of the (excellent) salad bar you're offering them.>
I've also fed them sinking algae pellets from time to time, but not often recently, as I think they are getting enough.
<Probably enjoyed by the Crossocheilus siamensis.>
I have so far always fed my goldfish plenty, up to three times a day. This partly because it amuses them (and me) and partly because I hope that by keeping them well fed they will wreak less destruction on the plants. In the past when they have gotten hungry they have destroyed many plants, so I try to avoid that because I want the plants to keep growing well to beautify the tank and improve the water quality.
<Provided there are plants in the tanks, your fish won't go hungry. So perhaps the way to work things is to establish the minimum amount of flake/pellet food needed such that your plants are basically left alone.>
Lately, however, I have had trouble controlling the nitrate levels in the water (my target is less than 20ppm, but I have trouble keeping it there). I have been experimenting with feeding the tank less often or less food at a feed. Yesterday I even went an evening without feeding them. To my surprise this morning, there was no great plant destruction. They must have been hungrier than usual, but they hadn't then uprooted everything in sight. This is really unusual, and rather a nice surprise for me, actually.
<Temperature is a critical issue I suspect: in warm water, Goldfish metabolism rises, and they become much hungrier. If the tank was allowed to stay cool, around 15-18 C, you couldn't keep the Crossocheilus siamensis of course, but the other fish would be fine and would eat much less food.>
Could it be that my goldies are entering a phase where they need less food or are less driven by hunger to explore/destroy everything in the tank? They can't be at their maximum size yet, surely - they have good water quality, good nutrition and an interesting tank, so I expected the larger two to reach 6 inches at least before they stop growing. I am wondering whether maybe the first year or so is a time when goldfish do eat more and get hungrier when they
aren't eating. If so, maybe I can look forward to being able to put more interesting plants in the tank and have them survive long enough to get rooted in and start to thrive - that would be nice :) Much as I like elodea, I don't really want the whole tank full of only that.
<Goldfish growth rate *is* fastest when they are small, but it otherwise carries on regardless of age, so that the older the Goldfish, the bigger it is. Temperature and diet both feed into this though.>
So, can you please tell me, how do goldfish nutritional requirements change in their first couple of years or with their first few inches? (Or maybe the right question is how does goldfish plant destroying change in their first couple of years?)
<Essentially this: give them easier alternatives to the live plants. Try Sushi Nori for example, or blanched curly lettuce and see what happens.>
Thanks very much,
Helen
<Good luck, Neale.>


damaged frog -05/07/08
Hi, I was out walking and found this frog in the road hit by a car he seems to be ok except for his back legs, the flesh is tore and bleeding slightly. he is not using these legs and I can't take him to a vet I hated to leave him there because I know a car would finish him off. My main questions are what can I put on his wounds? and what over all should I do for him? I have him in a tank with a little water on two paper towels. He can hold his head up but the two inner thighs are split down on the seams exposing his muscles with slight bleeding like I said before. He hasn't moved at all either just now he moved slightly
<Hello Candie. There's not much to do with a frog in this condition. In the wild this fish would be quickly eaten by a predator. You could certainly maintain him at home in a cool, damp enclosure with some water to paddle in and see if he improves. He probably won't eat much at first, but you could offer an earthworm or two. If he looks better after a few days, then consider "adopting" him for a while. We can offer some more detailed information on this issue down the road. Otherwise, painlessly destroying the animal is the most human way forward. Cheers, Neale.>

Re: Caring for Aquatic Hermit Crab 5/7/08
Hello again,
<Kathy>
I just wanted to thank you for you great advise. We have added a great variety to his diet and his color is already improving. He has also gotten a lot more active like he used to be. My not so little guy never stops. He has even changed into a much larger shell - he thinks he is bigger than he is. I just love to watch him.
Again, thank you for your help. I have pasted it on to my fish maintenance person so that he also can learn from it.
<Ah, thank you for this upbeat update. Bob Fenner>
Metal Halide Algae Nightmare! 5/7/08
Hi Gang! :)
<Lisa, lovely name (I married a Lisa)!>
I've been told for years now that my PC system wasn't bright enough for my Reef tank. I had an Orbit Extreme 4x130.
<What size/depth tank? Inhabitants?>
Anyway, I recently upgraded to a Coralife 150 with MH lights. The corals don't seem to appreciate it, the anemones hide from it and best of all, I've got a nuisance algae problem.
<A shock to the system on all fronts.>
Every week it seems I'm scooping this crud off the rocks, long, long greenish brownish algae that takes over everything.
<No fun.>
I've got two Tunze 6000s in the tank, a 30 gal refugium/sump with a protein skimmer, and a phosphate reactor. I just seem to be raising algae.
<It can be algae fuel if the ingredients are there, the lights merely ignited it.>
I keep the MH lights on from 10 a.m. to 5 p.m. only. Makes no difference.
<It won’t. Enough for livestock is enough for algae.>
I can't keep blennies, my Orchid dottyback attacks any new fish (or shrimp) I add to the tank and the blennies don't stand a chance.
<They can be aggressive, perhaps time to find that fish a new home?>
I'm sooo open to suggestions.
<Well Lisa, algae does not grow without the ingredients to grow it! There is excess nutrients in your tank coming from somewhere. Too much food, mechanical filtration or substrate accumulating detritus, inadequate skimming, etc. You will have to take a look at your system and figure out where the algae fuel is coming from.>
Thanks,
Lisa

R3: Help with SPS – 05/07/08
Hey Eric,
<<Hi Andy>>
I just wanted to give you an update.
<<Okay!>>
Although my AquaC isn't here yet, I did frag the piece of Monti cap with a Dremel tool to cut away the dying/bleaching portion.
<<Very good>>
It's a good thing, too, because the portion that was dying just sloughed off in my hand.
<<Mmm…a bad sign for sure>>
The remaining piece (I was able to save quite a bit) secreted a ton of mucus, which I assume was a response to the rough handling.
<<Yes…just “handling” in general>>
I dipped the piece in an aerated Lugol's dip for about 7 minutes, glued it back to the base rock, and placed it back in my tank. So far, so good--no further bleaching.
<<Excellent! It seems you intervened just in time>>
Thanks again for all your help.
Andy
<<Was my pleasure. EricR>>

RE: Tuxedo Urchin (mespilia globulus) spewing black substance -05/07/08
Hi Sara and Crew,
<Hi>
I would like to write a follow up regarding my initial inquiry about my Tuxedo Urchin, posted on your website on this page:
http://www.wetwebmedia.com/urchinbehfaqs.htm
Since writing you in mid-March, I have not witnessed the same occurrence from the urchin again. From the day it happened to present, the urchin
continues to roam the tank looking as healthy as ever. It appears to be eating and excreting as expected.
<cool>
I acquired the urchin on the 5th of January 2008 and it has always been in the same tank that it released the black substance into 60+ days later. As for the animal's diet, my thoughts are that the amount of time the urchin has been in captivity wouldn't be relevant in this case, would it?
<I don't know, it might be. Some animals take several months to truly "settle in.">
I'm thinking not, but anything is possible. If there is any instance that you know of where an urchin would release bile without any obvious stressors in the chemistry of the water or because of fellow tankmates, or if you have other ideas about what the substance might have been, I am still very curious to know.
<I'm curious too. I asked one of my friends who is a marine biologist. I showed him your video and he thinks it was either spawning or some kind of diarrhea. However, he had no information as to when, or why an urchin might have diarrhea. Whatever this was, it may or may not have been stress related. I'm sorry, but I don't think we'll ever know for sure exactly what this was or why it happened. If it happens again, try to collect a sample and take a look under a microscope. :-)>
Thank you for all of the work you do, and have a pleasant week!
<Thanks for the update!>

Cardinal with blister/worm? -05/07/08
Hello WWM Crew!
First, I have to thank you for the invaluable resource that you provide to all aquarists. Your website is brilliant: a veritable mine of information!
That being said, I (of course) have a problem.
<Thanks for the kind words.>
One of my cardinal tetras has me stumped. At first, I thought he/she had mechanical damage from running into something in their habitat. Later, a sizable white spot developed inside of a large, clear blister. Additionally, on this individual only, a large swatch of black has developed beneath the eyes bilaterally, stretching from the mouth towards his/her gills. The black "stripe" lies beneath the iridescent blue scales that cover the cardinals body. For the time being (and since the "blister" started to develop some time ago) the cardinal is acting entirely normal, schooling with the 29 others, eating extremely well, full cardinal colour, no scratching or abnormal behaviour. A second cardinal has begun to show the lighter/clear patch of discolouration that preceded the "blister."
<Ah, given the "syndrome" is spreading, I'm obviously thinking about Pleistophora as a possible cause. Whilst Cardinals do not seem quite as susceptible as Neons, they can still catch the so-called "Neon Tetra Disease". There's no known cure, beyond breaking the cycle of infection, which seems to be sick/dead fish releasing infective stages that get into healthy fish. Isolating symptomatic fish is the preferred first step.>
Tank specs: ammonia, nitrite, 0. Nitrate, less than 5, more than 0. Soft water, pH 6.8, mixed treated tap and RO. Fluorite substrate, heavily planted. Tankmates: 30 cardinals (two symptomatic), four M. altispinosus (asymptomatic), one SAE (asymptomatic). The tank has been fully cycled for about 6 months (fishlessly, so much easier! Why doesn't everyone do it this way?). The tank is kept at 82 degrees F. Partial water changes are done at least weekly (often times more often…there is still sediment on all of the plants from the Fluorite!) and the gravel is vacuumed each time (around the plants).
<All sounds ideal for tetras.>
I found a reference on WWM to worms growing in blisters on a Raphael Cat. Is this one and the same?
<Blisters can of course be caused by a variety of things. People get blisters from things as diverse as badly fitting shoes and Bubonic plague. So one should be very careful about assigning causes to just one symptom of this type. What's more specific to Pleistophora is changes in colouration, loss of appetite, shyness, and then eventually death. Infected fish, particularly species other than Neons, can last for many weeks even months before death.>
I found the reference here:
http://www.wetwebmedia.com/FWSubWebindex/catfshdisfaqs.htm . However, the same individual got two different answers from two different experts (you guys really are): "This is likely some sort of "worm" parasite (more likely a digenean trematode/fluke but maybe a nematode)… The Paragon might help... there are other vermicides... Levamisole, Fenbendazole, Piperazine... that might be tried" and "The blisters are really bacterial infections eating away the flesh of the fish. Treat with Nitrofuranace after you do a 30% water change and serviced the filter."
<Blisters can indeed be caused by both these things. Unless you're a microbiologist, it is really impossible to know what the problem is. So the best you can do is run through the likely causes one at a time, trying different treatments.>
There was also a reference to Dieter Untergasser's "Handbook of Fish Diseases": "There is one treatment method suggested in there that sounds like it should work (method C6)." I am afraid that I do not have this book, as I have never had any trouble with disease in any of my tanks (well, I rehomed African Cichlids for someone else that had been horribly abused, but that required nothing more than better husbandry and a larger tank). I checked local libraries with no success. I will purchase it now, but I'm afraid it will be a couple weeks to arrive. May I enquire as to this "method C6"?
<No idea I'm afraid. In any case, with very small fish, the fish often doesn't last long enough for the treatment to work. It's simply a size issue. So while I'd certainly consider isolating and treating infected fish as best as I could, in this case if it *does* seem to be "catchy", I'd perhaps painlessly destroy both fish to stop the problem spreading.>
If this is what is mal-affecting my cardinal(s), how should I treat? Should I treat everyone in situ or should I remove the affected individuals to the hospital tank? Do I need to tear down the tank to stop everyone getting infected if this is a parasite? Would they best be treated orally or as a bath? If I have to treat in situ, is there a medication that is plant safe, or do I have to remove the plants? I have attached a photograph of the cardinal (and learned that cardinals are camera shy, and move fast!) that shows the blister, white spot, and black under his/her eyes. I just noticed that the photo makes the cardinal look like it has popeye, but I can assure you that it is only a trick of the light.
<Isolate the infected fish for sure; perhaps maintain them for 2-3 weeks simply by providing good food and water and see what happens. Treat with an antibiotic or antibacterial if you want. It is possible the blister is nothing worse than a secondary infection caused by (for example) fighting. In this case, you should see some signs of improvement. But if the fish continue to deteriorate, get back in touch. At worst, you've isolated the potential source of infection and your other tetras should be fine. I have long since given up keeping Neons because of the plethora of mystery diseases they seem to come supplied with. Cardinals, though more expensive, are tougher and better value in my experience. But even so, you might be unlucky.>
Sorry for the novel of an email, but I wanted to provide you with all of the information I could. Thank you for all of your help, and the excellent resource you have compiled for all of us (it is becoming harder and harder to resist that reef tank…).
<So they tell me.>
To you and yours, a wonderful day and weekend.
Thanks,
Tianna
<Cheers, Neale.>

 

Crayfish parasites?
Hello Crew,
I have had my first crayfish, Claudine (Claude till I realized 'he' was a 'she'!) for four weeks now. She's a Cherax quadricarinatus. She shed her skin five days ago, and since then I have noticed some sort of parasite on her. I have scoured your website, but not found anything quite the same in the links.
They are opaque to white in colour (and seem to get whiter as they get bigger) and look like tiny slugs. I don't think they move that much, but certainly stretch out. They have little antennae of some sort, which wave in the water. I have spotted about five of them. The most obvious sits on her head (as in the first photo), she has another couple at least in the 'cavity' around the eye area, one nearer to her 'mouth' (second photo, you can see its head near the dark patch in the middle of the picture) which is very active when she feeds, and one in the joint of one arm.  I don't think they bother her, apart from the fact that she seems to 'blink' (flicks her eyes inwards!) quite a bit more than she used to. They really bother me though! I don't know whether this is normal for crustaceans as I have never kept anything like this before. The measurements for nitrites, nitrites ect. are all normal, and following the advice on your website, I have added a drop of iodide. Do you know what they are, and whether I should/can get rid of them? Are they harmful? I haven't attempted picking her up before as she's quite new and I don't want to frighten her. I think the only one I may be able to remove is the one on her head, but would need any advice on how to pick her up!
Many thanks indeed for your help,
Kathryn
<Kathryn, it's difficult to say precisely what these little animals might be. They could be parasitic, but it's more likely they are merely commensal, that is, they live on the crayfish but don't cause any direct harm. There are a few similar reports on the Crayfish FAQ page, here:
http://www.wetwebmedia.com/FWSubWebindex/crayfishfaqs.htm
In any case, treatment is likely impossible. Anything toxic to the "worms" would be poisonous to the crayfish. You could of course pull them off with tweezers or forceps, but at a risk of harming the crayfish. You could remove the next molt as soon as you see it, on the theory that might lessen the chances of re-infection (though crayfish do best when allowed to eat their molts and recycle the minerals therein). Bottom line, best left alone. Cheers, Neale.>

Calico Fantail Reproduction
How long does it take for a Calico Fantail to reproduce with itself? and how long till the eggs hatch?
<Depends on the water temperature. Goldfish are very difficult to breed in indoor aquaria (read: don't bother). In ponds, you basically leave them to it, and by the end of summer you'll have some baby goldfish. For more, see here:
http://www.wetwebmedia.com/fwsubwebindex/gldfshreprofaqs.htm
Cheers, Neale.>


Calico Fantail Gender
How do I find the tubercule and what does it look like?
<Aren't we doing "please" or "thank you" today? In any case, if you can't see the tubercles on your Goldfish, they either aren't sexually mature or aren't males. They're very obvious on sexually mature male fish. Look a bit like white spots, but symmetrically distributed across the face. Cheers, Neale.>

LPS ID -hitchhiker coral 05/07/08
Hello Dedicated Crew Member,
As I know you hear all the time, (from examining all the archives), your site is an excellent resource for any aquarist regardless of level. Thank you!
<Thanks>
I was hoping for some assistance identifying a live rock hitchhiker. I first noticed this guy about 5-6 months ago when he was around the size of a pencil eraser; it is now approaching the size of a quarter and
seems to be doing quite well. My first thought was that he was some sort of jewel anemone because of the presence of an oral disc and "jeweled" looking tentacles. I thought I'd give it a chance to develop into a pest or whatever it was and have kept a close eye on it. It has since changed drastically and looks more like some sort of LPS coral, reminiscent of an open brain. It now has multiple orange mouths and ruffled bright green flesh with the appearance of a stony skeleton beneath. I think there are 5 mouths in total. The tentacles are in a rough ring around each mouth. It happily eats any mysis shrimp that floats by and retracts to consume it. I have attached a picture (clear as I can get at this point) of the critter. I put in a few arrows marking the location of other mouths that aren't as easily discernable as the center mouth.
<The pic is a little blurry and so it's a hard to make out the underlying skeleton, but it does look like a member of the Mussidae family.>
You can also see a couple stalks of Neomeris annulata growing in the bottom of the picture. These grow regularly then end up breaking off and floating away and growing back on the same rock. Out of curiosity is
this the typical life cycle of this alga?
<I doubt it's part of the normal life cycle, but it might be some kind of survival mechanism.>
The bottom begins to deteriorate and turn whitish and eventually flake away while the top continues to grow in length and remains the vibrant green color. Is this attributed to fluctuating calcium levels?
<Possibly... or maybe it's due to a change in lighting, or perhaps even warfare with the coral. It's hard to say for sure, but here's a good source for more info on this algae:
http://www.algaebase.org/search/species/detail/?species_id=3736>
Any help would be greatly appreciated. Thanks!
Thanks!
Sam Bernal
<De nada,
Sara M.>
