Description: The Jack Dempsy is an elongated, laterally compressed cichlid. The base color is brown to black depending on the mood, condition, and population of the fish. Each scale is marked with a bright spot that depending on the light and water conditions can be gold to dark blue in color. Under these markings sometimes black stripes can be seen. Juveniles are less brilliant, having light gray or tan background color. Stressed fish will be lighter and their spots will be less striking. The male has pointed dorsal and anal fins; the upper edge of his dorsal is dark red: on the female the same edge is less brilliantly colored. Sexes can also be identified by the shape of the genital papilla; on the male it is pointed and on the female it is rounded.

Breeding is fairly easy in a tank with slightly acidic water (6.5-6.8 pH), a hardness of 6-12 dH, and an increased temperature of 82-84°F (28-29°C). An open breeder, the female lays a clutch of 500-800 eggs on carefully cleaned rocks. The fry are kept in pits, carefully guarded and attended by both parents. Start feeding the fry with small live foods.
