The Mbita Island population

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

About the species

Neolamprologus mustax is a small, deep-rock cichlid found only in the southern reaches of Lake Tanganyika, where it picks invertebrates from crevices in the rubble below about 20 m (65 ft). Its name nods to the pale "beard" on its chin — a trait shared across every known population — and it sits at the tangled boundary of the lake's yellow Neolamprologus leleupi complex, blurring into intermediate forms toward the Congolese shore. Modestly sized but fiercely territorial, it is a fish for keepers who want an authentic Tanganyikan rock specialist rather than an easy showpiece.
