I think I have green sunfish in my pond my phone won't let me download a picture but it's hard to tell my pond is muddy so the fish don't have much color but it has a lot bigger mouth than the bluegill and a rounder looking tail and has a brownish looking ear . I stocked red ear and bluegill so I don't know, they are bigger and they are eating feed , when I threw my jig out there I mostly catch them.My pond is only a few months old and I stocked it as soon as it started filling so I'm not sure what to think
