The Nkhomo Reef population

Nyassachromis breviceps "Nkhomo Reef" is the Nkhomo Reef population of Nyassachromis breviceps, a geographic colour form from the Malawi coast of Lake Malawi in the south-central part of the lake. It is the same species as Nyassachromis breviceps, distinguished by its collection locality and local coloration; aquarists keep and breed it as a discrete, provenance-labelled line.

About the species

Nyassachromis breviceps is a small, short-headed sand-cichlid endemic to the southern reaches of Lake Malawi. Described by Charles Tate Regan in 1922 from the lake's open sandy floors, it is one of the more cryptic members of the utaka-related genus Nyassachromis — a group of slender, plankton-feeding haplochromines in which the males build sand nests to spawn. Unusually for the genus, breeding males of this species reportedly seek out small stones to incorporate into their nests, and the fish is now rated Critically Endangered by the IUCN on the strength of its very small known range.
