The Thundu population

Maylandia nigrodorsalis "Thundu" is the Thundu population of Maylandia nigrodorsalis, 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 Maylandia nigrodorsalis, distinguished by its collection locality and local coloration; aquarists keep and breed it as a discrete, provenance-labelled line.

About the species

Maylandia nigrodorsalis is a rock-dwelling mbuna documented from a cluster of reefs on Lake Malawi's eastern, Mozambican-border shore, including Chiloelo, Meponda, Nkhungu Point, Nkolongwe and Thundu. Its species name, Latin for 'black-dorsal,' names the fish's most obvious field mark directly: a dark or black dorsal fin, set against the barred body pattern typical of its genus. Like its relatives in Maylandia, it is a narrow-range rock endemic whose identity is anchored to a specific stretch of reef.
