...know why? When I woke up this morning I saw the fish upside down and thought it died but when I moved the fish bowl it started swimming again but it keeps going upside down again.
If it has trouble staying upright, it could be a swim bladder disease. early detection is key. Peas are supposedly great for treating it. It could also be constipation. Try not feeding it for a day and if its upright and moving around like normal, its constipation. if it continues, give it a pea without the shell.
