Black Convict Cichlid (Archocentrus nigrofasciatus) CareSheet

The Black Convict Cichlid is a strikingly colored fish. This fish, also known as the Zebra Cichlid or Convict Cichlid, has black stripes on a grey background with a greenish tinge on the fins. The are also Pink Convict cichlids available in the hobby. The female has orange scales on her lower body and dorsal fins, but the male is bigger, has a steeper forehead, and longer fins. The male will develop a fatty bulge on the forehead as he gets older. They are a beautiful addition to any aquarium, but their aggressive instincts make them unsuitable for a communal tank.

A 30 gallon minimum tank with a gravel bottom, boulders, and lots of hiding spots among the rocks or inverted pots is required for the Black Convict Cichlid. As a kind of cover, floating plants are advised. Black Convict Cichlids should only be kept with other aggressive fish of the same size or bigger because of their aggressive behavior.

The Black Convict Cichlid is a cave breeder that can survive in a variety of water conditions. Increase the water temperature to 75-79°F to encourage breeding. Between a cave and an open region, several females will spawn. The male and female of the Black Convict Cichlid quickly couple and create a patriarch/matriarch family, with both caring for the young.

Both the male and the female will send signals to the fry. Most prepared and frozen meals, including freeze-dried bloodworms, tubifex, and ocean plankton, as well as flake food and Cichlid pellets, will be eaten by the Black Convict Cichlid.
