Nannacara

Nannacara is a genus of small freshwater cichlid fish endemic to South America. The genus is part of the Cichlasomatini tribe of the Cichlasomatinae subfamily. In the aquarium hobby, the fish is considered a dwarf cichlid along with Apistogramma, Mikrogeophagus, and Dicrossus species. Nannacara anomala is the most commonly encountered species in the aquarium trade.
