Consider a North Carolina native sunfish. They are beautiful and have loads of personality! These get to 6" - 8" max and a pair fit perfectly in a 29 or 55 gal.
There's something special about a native tank. It's hard to describe.
Check these beauties out:
Central Longear Sunfish
Pumpkinseed Sunfish
If he's frugal and ambitious, he can even catch his own for his aquarium.

I have 5 juvie longears that I'm raising from fry. They started at 1/2 inch and are now 1.5 inches and beginning to show their spectacular coloration. They are very active and greet me enthusiastically every time I approach the tank. They eat flake food with the occasional frozen bloodworm or brine shrimp.
