Sick Corydoras.

[Noahsfish]

I've noticed one of my 6 panda corydoras in a 20 gallon has what appears to be swim bladder disease..he can't keep from floating up. Is it a good idea to isolate him and treat him separately, and apart from peas and water changes, are there any other things that could help cure him? I moved him to a cycled and heated 5 gallon, shut the lights off and am preparing to do a 50%ish water changes daily. Should I move him back to the main group? Oh, and the inhabitants of the 5 gallon are RCS and a dwarf puffer...I know the dp could cause problems, but she's still young and fairly docile seeming.

Maybe fast him for 3 days then feed him the pea?

Wooooow, ok, this tank went downhill very fast! I came home about 25 minutes ago and found lots of dead fish...the stocking was

6 harlequin rasboras
6 panda corydoras
1 dalmation Molly

I do water changes every other day and vacuum substrate. Water sits at 77, lots of plants...no chemicals added. Didn't even notice, but I guess my rasboras are very Ill as well....I found 2 of them dead and another 1 of the corycats wedged under a decoration (still breathing). The rasboras are covered in this white, almost mucus looking stuff...its like a horror seen watching them trying desperately to school, I just now removed the Molly into a 2.5 gallon temporarily because he was pecking at them....I'm really at a loss as to what to do, I'm scheduled to leave Monday and was planning on bringing the fish in sunday. I was planning on shutting the tank down and giving all the fish to a lfs..now I have 4 very sick rasboras, which I won't be surprised to find dead, a dalmation Molly who could be diseased in a small 2.5 gallon (cycled and heated) and 6 corycats 2 which are pretty much gone.

Wow, and just yesterday everything seemed fine, never had a tank go downhill so fast....nor this many casualties, it's really despressing ;(.

Sorry to hear
Any idea what's happened? What are the stats like?

This may sound stupid, but you used water conditioner during water changes right? (Just ruling out any possibility)
And I feel you, I had awful luck with corys, losing them all despite having ideal water parameters, tank, and diet. They died one by one of the same thing almost instantly. I think these guys are very sensitive so even the smallest thing can harm them, or even kill them. Sorry to hear

Think you got in a minicycle. Test Ammonia and nitrite (esp. the first one).
