These would be good choices, Nicaraguense are really great fish and have alot of color when they grow. The only problem is a male can max out at 10" but not often in a aquarium. females are smaller.You could maybe get a dwarf pike cichlid if you are into those, Salvinis are great fish but sometimes tend to hide a little when they mature and in a small tank you might not be able to keep another fish with the salvini due to aggression. A pair of convicts or honduran redponits would be great also.Yes either one of those would work along with another hundred or so from South or Central America. I'd look into cichlasoma nicaraguense, cichlasoma salvini, and Cryptoheros sajica would would be some of my personal choices.
