I swear this one of mine looks like it is going to explode. If it wasn't swimming all over the tank eating more pods I would think there was something wrong like an intestinal blockage or something. I have another in a different tank that while pudgy is no where near as fat as this one. I'm not really concerned just more curious if anyone else has one this fat. I don't remember having a fish this fat. Pics are not great because the fatty refuses to stay still. He has those pods to chase down lol.
