For the American Cichlids any of the apistos in that size tank, german rams or the bolivian rams would be perfect. With these you could even go with a fast school of tetras like rummy nose and make a descent community tank.
African kribs will breed like crazy in that size or any shell dwellers. My favorite being multifasciatus.
