Yeah, certainly a green sunfish, but a pretty one at that! They get mixed in with all kinds of tropicals at LFS. I've seen them with Mixed Africans, feeders and labeled as "South American Cichlid."
Sunfish can be aggressive and territiorial at times. I've had ones that were peaceful and got along fine with tankmates and ones who needed to be solo fish. However, I've kept several different tropical and SA cichlids and nothing compares to the personality I've seen in Sunfish, Pumpkinseeds and Largemouth Bass. It might not be what you're looking for, but I'd do some research before taking it back, you might enjoy having him!
Head over to the Cold Water, Temperate and Natives section of MFK, there are a lot of articles on green sunfish and I think you'll find a lot of helpful information there!
