One of my fish is swimming nose up and tail down. He keeps swimming like that, been that way for a few days. What should I do? Should I put fish to sleep, or is there anything else I can do? I do not have any peas to feed him. I do not know if the fish would eat or not, even if I did have it. Is swim bladder painful to fish? There is something wrong with my fish and I do not know what is the right thing to do, thanks!
