The Kaswente Bay population

Neolamprologus tretocephalus "Kaswente Bay" is the Kaswente Bay population of Neolamprologus tretocephalus, a geographic colour form from the Tanzania coast of Lake Tanganyika in the 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.
