So I was out bass fishing with my son this afternoon and caught this sucker.  I caught him in about 7-9 fow with a finesse worm on a shakey head jig.  He looks like a small mouth but had a very yellow belly and very distict orange/reddish color fins.  It wasnt like bloody fins like you typically see in spawning fish it was a bright orange.

Green sunfish very common bass prey.

Warmouth is a close relative, bigger mouth.

Green sunfish... 

Awesome thanks for the help guys. This one is a first for me.

They are fun to catch... spunky as hell.  Pound for pound, I think they pull like a smallie.

Watch out though, they are prone to pee on you.

It's a warmouth,

 

Green sunfish are very similar, but tend to have more blue on the gill plates and sides, the fins are typically orange if they have any colors, and of the untold numbers of green sunfish I've caught, I've never seen one with color on it's dorsal while the warmouths I've caught have it quite frequently.
