The coloring of this cichlid is amplified even more when it is spawning and often results in the female presenting more vibrant coloring than the male. A fish in excellent condition will develop intense black and gold colors along with some bright reds and some blue highlights. Females develop a reddish coloring along the belly and back, though some males may get a reddish belly too. Females also get a blue edged black spot in the middle of the dorsal fin and another black spot on the edge of the gill cover. Males will develop blue streaks on the head and can have blue hues along the back.
The Black Belt Cichlid is usually available online and sometimes in fish stores. They are moderately priced for juveniles.

Rift lake cichlids express timidness and dominance through color. A pale fish is a stressedor timid fish, whereas a very dark fish is a dominant or aggressive fish. The dominant male willhave deep vibrant colors or possibly be almost entirely black. Physical description: This cichlid has an oval-shaped, laterally compressed body. The head is rounded and the caudal fin is fan-shaped. The anal and dorsal fins come to a point. The base body color is white to dark gray with a characteristic wide, transverse black band that is located around the mid-section of the body. Sometimes the band may be broken, while at other times the band runs unbroken from the tip of the mid rays of the dorsal fin, down to the belly. The throat to the lips is bright red as is the caudal fin. Depending on the color variation, a portion of the scales may be spotted. A black area encircles the eye and often includes the iris. The anal and dorsal fins have black spots, and the last rays are red. In some variations the rays leading up to the red parts are yellow and green before becoming red. Some variations have a short, broad, lateral marking on the caudal penuncle. Older fish, especially males, develop a hump on their forehead.The Black Convict Cichlid requires a 30 gallon minimum tank, with a gravel bottom, rocks and plenty of hiding places among the rocks or some inverted pots. Floating plants are recommended as a form of cover. Because of their aggressive nature, Black Convict Cichlids should only be housed with other more aggressive fish of the same size or larger.Auratus cichlids are small, elongate fish that can grow up to 11 centimetres (4.3 in). Juveniles and females are bright yellow with black and white stripes on the upper half of the body. Adult male coloration is drastically different with dark brown or black body and light blue or yellow stripes on the upper half of the body.The Convict Cichlid is probably ranked number 3 out of all cichlids as far as popularity goes, with Angelfish and Oscars being 1 and 2 respectively. Convict Cichlids have the common name of "convict cichlid" because of the white and black contrasting patterns they sport. Males may be larger than females of the same age and the females may have a pink or orange tint to the belly region. There is an Albino Convict Cichlid as well. This fish can get to be about 4 inches (10 cm) and should do fine in a 20 gallon (78 liters) or larger aquarium.In this weeks episode of iN-dEPTH we take a closer look at the Black Convict Cichlid. This aggresive cichlid is one of the most well known freshwater fish due to it's ability to reproduce like rabbits and be able to survive in a wide range of water parameters. Enjoy!
