The Mulyma population

Neolamprologus mustax "Mulyma" is the Mulyma population of Neolamprologus mustax, a geographic colour form from the Zambia coast of Lake Tanganyika in the southern 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 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.
