Problem:- three days ago I woke up to one of my salmon tail catfish floating upside down at the top of the tank. As soon as he saw me approach the tank, he spun around and seemed fine, although a bit weak. I partially changed the water and fed him a shelled pea. He seemed much better that night and the next day. I fasted him until last night. I only gave him a few flakes, however I woke early this morning to him floating upside down again. He ate another bit of pea and he is swimming a bit better now. Does this sound like constipation, swim bladder issue or something else? I read that if it was swim bladder, he would be having balance problems continuously, not just every now and then. He seems to have a lot of fight left in him. Any advice would be greatly appreciated.
