Urgent!!! Help PLEASE!!!!! Angelfish fry deaths 9/26/05
We have been breeding Angel Fish for approx. 6 yrs now.  We have come across a problem we can't seem to find a remedy for.  All our fry are dying within 3 days of hatching and never seem to come up to swim.  We have quite an elaborate system set up in our basement.  Each tank having its own filtering system (to avoid cross contamination from other tanks) and a large holding tank where the water is filtered, heated and tested before use in changing water in the fish tanks themselves.   Currently we have 1-150gl tank, 9-70gl tanks, 1-35gl tank, 3-30gl tanks and 4-10gl tanks.  Our 10gl tanks are the ones we use for fry hatching away from the parents.  We are on a well water system.  3 months ago we had a lab come out and test the water in the well.  All came back within normal limits with Iron (Hard water) being just a tad on the high side of the normal, but still within the normal limits.  
Our batch that hatched 2 days ago were all found dead this morning.  Out of no where it almost looks like white dust floating all in the tank.  What ever it is, they appear to be floating/swimming on their own.  Not so much as ONE fry is left anywhere to be found.  Only these white specks.  Is it possible, that when the well water is brought up to temp in a tank, it wakes up some kind of "bug" (for lack of a better word) that is killing our fish??  Have you ever heard of anything like this before or are aware of anything to correct this problem.  We are quickly running out of Angels here and it is becoming very frustrating.  We have checked and double checked all levels in tanks, holding tank and well system and can't seem to come up with any reason our fry keep dying off.
>> I would have to guess, but it is likely that you have a parasite on the loose in your tanks that is not affecting the adults. Best guess would be Cryptosporidium which is famous for killing fry. You can treat the water with general antiparasitic medications and see if this resolves the problem, after that you should check to see if there is maybe some heavy metals in your source water that are affecting the fry.
Good Luck, Oliver

Neon Tetra help needed  - 03/28/06
Hi. <Hello>  I have 5 neon tetras, 3 Zebra Danios and now 3 Fancy Guppies (1 female and 2 male) with about 7 fry hiding (mom died)<Sorry to hear that>.  When I bought my Tetras they were all fine until the next morning.  1 had lost its color from midway on back and was swimming funny (like it was drunk).  It has now regained its coloring and swims better.  However, it goes in fits of twirling about (fast circular movement; head down) and other times I can't tell which one it is in the school.  What is wrong with it (maybe got injured on the way home)?  I grew up (25 years) with Tetras (as well as the other types) and have never seen anything like this.  Do I need to remove it from the tank or is it ok to leave it in there?  Thank you, Karen in Georgia. <First, remove the Neon to another tank. What you describe, to a large degree, mimics "Neon Tetra Disease"; loss of coloration, erratic swimming behavior. I've not come across any information that describes the return of color to a fish once it's been infected, though, which makes me wonder, to be honest with you. There is a "false" version of the disease which is bacterial rather that sporozoan in its cause but it would be virtually impossible, outside of a laboratory, for you (or I) to discern the difference. Since NTD is spread to other fish so quickly and with such fatal results, you should treat this as a "worst case" to protect your other pets. Unfortunately, there is no known treatment for NTD although some claims of success have been offered; none conclusively, I'm afraid. Maintain your water parameters in the main tank to protect against any spreading of whatever this may be. Best of luck to you, Karen. Tom>

Myxosporea?  Myxosporidians? - 03/14/2005
Hi Bob,
<Actually, Sabrina with you today.>
I have read/searched through WWM and have been unable to find much regarding Myxosporea.
<Mm, try "Myxosporea", "Myxosporidea", "Myxosporidian"....  And try via Google, as well.  And, especially, try here:  http://www.fishdisease.net/ .>
I had 3 black phantom tetras, 3 cardinal tetras, a male Betta and a Pleco in a 10 gallon tank.  (probably slightly overcrowded but frequent (25% 5-6 days) water changes has kept the water quality very good.
<Can't attest to bioload, as I don't know the tank size.>
Anyway last week  I had a fish (bp tetra) start showing all of the swimming signs of Myxosporea but none of the other symptoms.  
<Myxosporea are simply a group of Sporozoans, protozoan parasites of fish....  I wonder if you're thinking of the Myxosporidean Myxosoma cerebralis, or "whirling disease"?  I'm not certain that tetras are susceptible to this....  Uh, in any case, what were the symptoms you saw?>
He succumbed to wounds sustained in an attack by the Betta which I happened to witness (lost an eye, severe fin damage).   I was not quick enough to get my net and rescue the poor fish.  Anyway now that I have carried on for a while I was wondering how I should deal with this so as not to start an epidemic and lose all of my fish to this slow but fatal disease.  
<Are you seeing any symptoms of any sort in any of your other fish?>
I have a 3 gallon "hospital tank" plus another 1 gallon jar that could hold the Betta if need be.  I am fairly new at this hobby and do not want to fail miserably within the first year.  Thank you in advance for the help and keep up the good work on your site.  
<And thank you for your kind words.  Hopefully a little more information will shed some necessary light, here.>

Gold veil angel rams
I recently purchased 5 gold veil angel rams from my LFS.. they normally get them twice a year and are gone as soon people realize the store has them in stock so I decided to go on ahead and buy them even though they seem to have what looks like as an internal parasite or tumors or something of the sort.  besides.. at this point I'm curious just to know what exactly is wrong with them and how to properly treat them or if it's even at all possible to treat them.
the "tumors" as we'll call them are about 2-3mm in diameter, oval shaped and brown or gray in color.  you can see them through the body of the fish as they are somewhat translucent.  they don't show any signs of struggling.. they are responsive to stimuli, they eat regularly and are all housed currently in a 5 gallon quarantine tank with no substrate and a sponge filter as you would find in a fry tank.  
they are currently being treated with a 1/4 teaspoon of paragon every other day with a 2-3 gallon water change every fourth or sixth day.  I've had them for about a week and they don't seem to be getting any better, but they aren't getting any worse either.  I was wondering if this really could be a parasite or infection and if I'm treating them with the proper medication.  I have also given them a salt bath using freshwater salt but could only do this for around a minute or so before they were beginning to float on their sides.. I thought I was sure to have killed a couple doing this but I quickly moved them back to the 5 gallon tank and to my surprise they all lived and returned back to their normal state.  if you have any suggestions I'd really appreciate it.. even some background information on the fish would be great as I know they are relatively new to the stores, or at least here on Oahu.. in fact.. this is the only LFS on the island that ever gets them.. hence why I thought I may risk buying these ones.  I have called the LFS since to check about the rest of the fish to find that they too aren't getting any better either.
< Many of these parasites that infest the body of the host are difficult to treat because the tissues of the fish prevent the medication from getting to the parasite. The other problem is when the parasite dies then this dead thing starts to decay and rot inside the fish. Sometimes these things are parasites that have numerous hosts. They start out in a snail and then invade a fish. The fish gets eaten by a bird and excretes the eggs of the parasite that then hatches and lives in a snail for a while and starts the cycle all over again. I would quickly try and breed the rams and start a parasite free generation.-Chuck>
thanks again

Nalagram & neon disease
Bob,
    The reason I'm contacting you is that there seems to be so few people that have used Nalagram on this disease and have a good report.
It seems the more I study up on it , the more conflicting things I come up with; all the way from curable to tear it down and start all over from a sterilized scratch.
   I have a lightly populated 140 gal. heavily planted tank. The fish, really, are secondary to the plants. Did you use the product in a planted tank ? And if so-- did it adversely affect the plants ? Any information you could give, or advice on how to use this product in my tank would be greatly appreciated. I have 6 packets of the Nalagram tabs
on their way. So far, only one of 16 Neons is displaying the disease.
            Thanks for any advice you might e-mail me,
                                           Bill Mandeville
<This compound, Naladixic acid, a quinolone, has been used with mixed results by me, and others... more mixed in more recent years... It does/should not adversely affect plants, unless so much is used for so long as to alter your water chemistry severely (through biological processes/collapse)... On contemplation, thought I might have the time to put into a more complete set of statements about this malady, its "cures"... and the Upjohn co. product... Instead, please read through "the krib" archives of The Aquarium Gardeners Association for this.
