The goldeneye cichlid (Nannacara anomala) is a species of cichlid found in fresh water from the Aruka River in Guyana, to the Maroni River in Surinam. It is often found on flooded savannas near the coast. The male grows to a length of about 5.6 centimetres (2.2 in) while the female is somewhat smaller, and is thus regarded as a dwarf cichlid. As youngsters, there is hardly any difference as a juvenile male does have the colouration of a female.The only difference would be the presence of an extension at the back of the male's dorsal fin.
