Cyphotilapia frontosa is a fish from the cichlid family native to Lake Tanganyika in East Africa. C. frontosa is endemic to Lake Tanganyika and is widespread in the northern half of the lake, whereas the closely related Cyphotilapia gibberosa inhabits the southern half of the lake. Unlike many cichlid species C. frontosa is a pelagic fish and rarely ventures close to the shoreline. The species generally resides at greater depths (30–50 metres sub-surface) than most other cichlids and rises to shallow waters in the early morning to feed on shoaling fish such as Cyprichromis species. C. frontosa can grow to a significant size with even captive specimens potentially growing to 35 cm in length. The fish can live for over 25 years.
C. frontosa has distinct markings with 6-7 black vertical bars adorning a white or blue body and head and trailing fins with a distinct blue hue. The species also develops a nuchal hump that is more pronounced in older specimens. C. frontosa is a sexually monomorphic species, although the hump is occasionally more pronounced in males. As is the case with many of the cichlid species found in Lake Tanganyika, parallel evolution between distinct breeding colonies has resulted in several different colour variants developing.
