The Mkuyu population

Neolamprologus tretocephalus "Mkuyu" is the Mkuyu population of Neolamprologus tretocephalus, a geographic colour form from the Tanzania coast of Lake Tanganyika in the north-central part of the lake. It is the same species as Neolamprologus tretocephalus, distinguished by its collection locality and local coloration; aquarists keep and breed it as a discrete, provenance-labelled line.

About the species

Neolamprologus tretocephalus, the five-bar cichlid, is a stocky rock-dweller endemic to the northern half of Lake Tanganyika, instantly recognizable by the five bold black bars on a pearly blue-grey body. It is a snail-crushing carnivore of the shallow rocky shore and a famously belligerent fish, capable of holding territory against far larger tankmates. Long mistaken for a peaceful dwarf because of its modest size, it is in fact one of the more uncompromising lamprologines an aquarist can keep.
