Archocentrus is a small genus of cichlid fishes from Central America. The genus currently contains 3 species. It formerly included 7 of the species now included in the genus Cryptoheros, as well as the convict cichlid, now included in the genus Amatitlania. The Rainbow Cichlid, Archocentrus multispinosus, was formerly included in the genus Herotilapia. A 2008 study led by Oldrich Rican suggested that the Rainbow Cichlid is actually more closely related to the Jack Dempsey (genus Rocio) and the cichlids of the genus Astatheros than to the other Archocentrus cichlids, and thus should be moved back to the genus Herotilapia.
