I have a Convict in a tank with other Cons, Jewels, Kenyi, and RedDevil. 55g, pfs for substrate. Doing my weekly water changes, I noticed 1 Con on the bottom having issues being neutrally buoyant. He seems to sink rather quickly, not drift down but sink to the bottom, I just tried to see if he was still doing it now when he was asleep. He does. Everyone else is fine, eating like pigs.

So far, changed 50% instead of 25%. Jacked heater to 80 degrees, and treated with salt.

Any other ideas?


the only other thing, I used to have crayfish in the tank, they were just eaten, did the con get to much crayfish? pop his swim bladder? eat sand?
 
I wonder if your fish is constipated due to eating the crayfish. Such a circumstance could cause sinking. Does the fish have a big belly or have you seen it poop?
 
It doesn't appear bloated, in fact, it looks slightly thinner than the tank mates. Haven't seen it poop. Plan on doing another 50% water change just in case it's ammonia poisoning, but I don't think it is. No red gills/ fins. Everyone else more than content. The only other thing could be "exhaustion" the kenyi, and red devil are newer, but have been in the tank for a month now. Nothing else seems amiss.
 
still sinking, separated him to a Q -tank. Still giving salt and heat. Appears to be curving. Not looking good for this one. On a plus side, my other Convicts are breeding. Not like that is the first time Convicts bred.
 
Its probably swim bladder infection is what im thinking, my 8inch dovii does the same thing he just sinks. He will still eat and ram the tank when i get near him but he just sinks im adding salt to it in hope it helps but for now ill just have to deal with it
 
yeah he pooped a little, still sinking like a stone. Might just be that way for him, and throw him back into the main tank.
