The Kambwimba population

Neolamprologus obscurus "Kambwimba" is the Kambwimba population of Neolamprologus obscurus, 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 obscurus, distinguished by its collection locality and local coloration; aquarists keep and breed it as a discrete, provenance-labelled line.

About the species

Neolamprologus obscurus is a small, dark-bodied lamprologine cichlid endemic to the southern third of Lake Tanganyika, where it lives a secretive life wedged into the crevices of sediment-rich rocky shores. It is best known to science not for its looks but for its social life: it is one of a handful of fishes that breed cooperatively, with grown offspring staying home to help raise the next brood. Most remarkably, those helpers excavate and maintain cavities under stones that trap drifting shrimp, effectively farming the family's food supply.
