Description

The blackfin mbuna is a rock-dwelling cichlid (mbuna) endemic to Lake Malawi in East Africa. The species grows to about 12 cm; males are dark with a blue sheen and black fins, to which the name refers, while females are lighter yellow-brown. It lives over rocky bottoms along the shore, where it is territorial. With its mouth it scrapes the growth layer of algae and small invertebrates from the stones. It is a maternal mouthbrooder: the female incubates the eggs and larvae in her mouth. The species is popular with aquarists and is harmless to humans.
