A single breeding pair of apistos, rams, or any other dwarf cichlid species are fine in a 29 gallon. Some apistos are hardier than GBRs, but not always. Bolivian rams are the only ones that universally tend to be less sensitive. The vast majority of of them are usually fairly community friendly, though some tend to get more irritable than others when breeding.
