features
Males of Steatocranus tinanti reach a length of up to 15 cm, females remain significantly smaller at 10 cm. The species is a very slender and elongated representative of the genus Steatocranus and, together with the humpback cichlid ( Steatocranus casuarius ) known from the aquarium hobby, has the clearest sexual dimorphism . The males develop a forehead hump, which gets bigger with increasing age and have a very massive mouth. In both sexes, the dorsal and anal fins are clearly drawn out in the soft radiating section. The tail stalk is long; the large caudal fin is elongated.
Steatocranus tinanti is usually uniformly gray or olive yellow in color, occasionally they show two dark longitudinal bands or 4 or 5 transverse bands on the sides of the body. The fins are gray, brownish, or colorless. There is sometimes a dark area in the center of the dorsal fin.
