(Lamprologus callipterus)
Lamprologus callipterus is a species of cichlid endemic to Lake Tanganyika where it very actively moves about in search of crustacean and other invertebrates. Males of this species can reach a length of 12.4 centimetres (4.9 in) TL while the females only grow to 4.5 centimetres (1.8 in) TL (see below). This fish can also be found in the aquarium trade, though it is considered to be poorly suited for captivity.
