The Itungi population

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

About the species

Nyassachromis microcephalus is a small, short-headed sand cichlid endemic to Lake Malawi, described by Ethelwynn Trewavas in 1935 from Monkey Bay. One of the smaller members of its genus, it lives over open sandy shallows and feeds on plankton in midwater, forming small schools. Like its relatives it is a sand bower-builder: breeding males heap up a sand turret topped by a distinctly slanted spawning dish, a structure close to that of Nyassachromis purpurans. With an apparently lake-wide distribution and a healthy presence on suitable sand, it is rated Least Concern by the IUCN.
