Re: What type of sunfish is this?
Nope, most definitely NOT a green sunfish. Colors are wrong, shape is wrong, mouth is too small. However, it could be a hybrid between a green sunfish and a redear or even a bluegill. Greens hybridize readily with both species. And oddly enough, I've got a sunfish in my aquarium that looks almost exactly like that one, which I believe to be a green/redear hybrid.
