Boy, it sure pays to be able to identify fish. To me that would have just been a biiiiig Bluegill. The varieties of panfish identities confuse me. I can tell a shellcracker from a bluegill, but that's about it.
Flier, green sunfish, etc. Can't tell 'em apart. I could probably pick out a Pumpkinseed. But I couldn't tell if a redbreast was actually that, or something else with some red coloring in its breast. Warmouth is easy to spot.
