I have a poorly juvenile tri-lin. He is only little about 2-3cm's. I noticed the other day that his tail looked a bit ragged - but he seemed ok happily looking for food with the others.

Yesterday I noticed that his left pectoral (??) the one that would be his arm if he were human was missing

I dont understand it because there is nobody in the tank who is vicious - other tank mates are sterbai's, khulie loaches - black and normal, polka-dot loaches, rainbows, harlequinns and danios. The only culprits may be the two female opaline gourami's but I've watched them for days and they dont go near the cories???

Could it be the black khulies???

Either way - my question - he seems happy enough, swimming about ok, eating - just doing normal cory stuff. Is he better off in the main tank with everyone else or in the hospital tank? I'm just concerned about him feeling isolated in the quarantine tank on his own - or should I put some of the other cories in with him for company??

Any ideas???

One of my trilineatus has a missing fin. I have no idea how it happened but he or she does not seem to be affected at all. Add some melafix to the tank and keep an eye out for aggression. In my opinion moving the fish may be more stressful than helpful.

I am with wolfwolf.

I have a little albino pepper that is missimg the pelvic fin that they balance with. I don't know how it happened. For all I know he was born that way. It is hard on him because there is a lot of water movement in the tank and he is blown over often and lays on his side. I have put him with other stray Corys, because I don't want him to breed if he is a deformy. But he is a game little guy. I doubt he knows the difference, and imo life is always better than death. Well sometimes with animals I would have to end suffering.
