Personally I would recommend any of the following. Flowerhorn, Oscars, Jaguar cichlids, red tiger motaguensis, King Kong parrots, bichirs, Cuban cichlids, red devil's, Midas, trimacs, vieja, green sunfish, warmouth, rock bass, bluegill, yellow perch, European redfin perch, fresh water eels, crappie, mbu pufferfish, and many other fish I just can't remember atm.
Btw I understand the whole fisherman family life style. It won't stop at game fish. Lol can't remember how many times someone has told me "o that fish looks pretty, it's pan sized too, when are we eating him?".
