The Nkolongwe population

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

About the species

Melanochromis melanopterus is a small, dark rock-dwelling cichlid (an "mbuna") endemic to Lake Malawi, and the fish for which its entire genus is named. Where most of its yellow-and-blue relatives advertise themselves on the reef, this one blends into the shadows of the rock pile and earns a living the hard way: ambushing the fry of other cichlids. Unobtrusive in the wild and uncommon in the trade, it is one of the more cryptic members of one of the planet's most spectacular fish radiations.
