I adopted this guy about 2 months ago from a fish store that I buy all of my fish from. He was found in an abandoned house, floating upside down in a tank with just a few inches of water. I assume his diet consisted of what ever fell in the tank. He had been in the store for about 2 weeks before I got him and he was on a all-pea diet. They gave me some swim-bladder disease medication to help him but it seems like it's done nothing. He's also been on a diet of nothing but peas for 2 months. He's gone 10 days without food before and the problem still remained. I just put him in his own 20 gallon so he could eat his peas with out the other fish getting to them first. As time goes on his side is getting bigger and bigger. When I put pressure on his side it feels like he's full of air. I'm getting really desperate and thinking about taking him to a vet that performs surgery on fish. Does anyone have any advice? Thank you!
