Midas Cichlids are known by the scientific name Amphilophus citrinellus but have previously been classified as Cichlasoma citrinellum, Heros citrinellus, Heros basilaris, Cichlasoma granadense and Erythrichthus citrinellus. The coloring varies significantly for this species, probably because of the ease with which they are bred. Many are grey with black horizontal banding. Yellow, orange and gold are also common coloring, giving rise to the name Midas (Gold).
