I have a baby bass and a baby channel catfish in a tank and they both seem to be flashing a lot and the bass swims eratically. I can't see any signs of any infections or anything and have read that aquarium salt can help ward off fungus and other bacterial infections. I also recall reading somewhere that salt can be bad for catfish cause they have a skin instead of scales. Anyone got any advice on whether you think it would be a bad idea or not to put some aquarium salt in there?
