Description: Gunther's cichlid can change colors quickly and will exhibit many different combinations, possibly according to mood. There are two sub-species: Ch. guentheri guentheri, and Ch. guentheri loennbergi. The male is larger, and the female has a broad, shiny silver or mother-of-pearl crest on the dorsal. Females are more brightly colored. Females also have a pinkish belly with a metallic white stripe on their dorsal fin. Although mouthbrooders, they are monogamous, make excellent parents and form permanent pairs.

Chromidotilapia guentheri spawns openly, dropping up to 150 eggs which are then taken by male. When free-swimming the fry are cared for both parents. At this time female will accept the fry at night or in times of danger. The fry can be fed on newly hatched brine shrimp.
