Juvies With Clamped Fins?

[ezrock]

hey. for the last few weeks, my juvies have been dying off. I'm down to 4 or 5 of my spawn of 9. I've treated with anything I could think of that might work and nothing has. They seem to only get it one at a time, and isolating the sick fish never seems to help. They eventually lose their ability to stay horizontal, but soon after that, their fins start clamping down, usually starting with the anal fin, then eventually the caudal and dorsal fins too!

Does anyone know what this could be? There are 4 juvies in a 5 gallon. It didn't affect my two guppies that I had in the same tank for a week. Water temp is 81F. They were born on Jan 15th, so they're about 3.5 weeks old (and small compared to hardcore breeders' fish at this age but that's partly bcc the biggest ones started dying off first several weeks ago).

Here's the best pic i could get (don't mind the algae )


Thanks for any help!!!

Need to look at your water quality in ammonia,nitrite,nitrate,and ph, bad water quality can cause swim bladder problems.

Hi. I'm aware of that, but I don't think it's really a swim bladder problems due to the clamped fins. Plus, I thought swim bladder problems were due to internal parasites, which I've treated for with no luck! They're in a well-aged tank that gets frequent water changes, so the water quality is not sub-par.

Whenever my fish are sick and I can't tell exactly what the problem is, I treat with a cocktail of salt, Melafix and whatever parasite med that contains Malachite Green I have handy. Works like a charm 9 times out of 10

Hey,
This may sound obscure but sometimes bad cases of finrot can start like that. It happened with one opf my ram's once, Treat the tank with some melafix and some anti-internal bacteria solutions.
Then let's hope your fish are as right as rain.
Must be devisateing seeing them die.

thanks synirr and animation!

I think it's a bit too late to save the last one that is showing signs. One still remains fine in that tank, and the one i removed about a week ago is doing very well in a 10 gallon with 2 guppies.

I gave two to a cousin as a form of separating them from the sick ones....but I don't know how well they are, because I haven't talked to him since.

I'm just hoping I can keep the last two healthy ones I have healthy!!! If I see signs starting with these two, I'll be dosing right away with your suggestions

could it be a bred disorder? because its effected ya whole batch and you seem to have tried alot and hosp tanked them etc?

 

[ezrock]

somehow I doubt that. It was a huge outcross. The parents were two different tail types (completely) so they were VERY unrelated and the kids wouldn't be inbred (unless you go back 100+ generations I would guess theoretically ).

Anyways, I have some good news. I've taken them fully off of any form of flaked or frozen foods. They are getting just microworms right now, which they are avidely eating. Their fins are fully unclamped (the remaining three here and two at my cousin's). But, two of mine in one tank still seem to have what looks like swim bladder problem (the third one I separated early and he's doing awesomely in a 10gal planted with steady current and two guppies). I don't want to treat the other two quite yet, because I've thrown lots of other stuff at them already. But, if it comes down to it, I have a bunch of new meds I got from my cousin so hopefully there's something else in there I might be able to use!

I'm just glad they're taking a turn for the better finally!
