I totally agree and would like to add I have never seen one with so much red in before.....very nice! I would give him some driftwood and rocks in the aquarium and Im sure he will feel right at home. Ive always wanted to make a Redbreast/ Green hybrid just to see what it would look like.Noto;4588524;4588524 said:It's a redbreast sunfish, AKA shellcracker, Lepomis auritus. They are similar to longears, but the longear does not have the colored fin margins, and usually has white on the edge of the dark "ear". Yours is a male; females and non-breeding males have yellow fin margins.
