The Mtosi population

Neolamprologus timidus "Mtosi" is the Mtosi population of Neolamprologus timidus, a geographic colour form from the Tanzania coast of Lake Tanganyika in the central part of the lake. It is the same species as Neolamprologus timidus, distinguished by its collection locality and local coloration; aquarists keep and breed it as a discrete, provenance-labelled line.

About the species

Neolamprologus timidus is a slender, dark-bodied Tanganyikan cichlid that spent decades hiding in plain sight, lumped together with its near-twin Neolamprologus furcifer until a 2014 study teased the two apart. Endemic to a roughly 62 mi stretch of the Tanzanian coast, it lives pressed against the undersides of boulders and the back walls of deep caves, often hanging belly-to-rock with its head pointing down. Its name, Latin for "shy," captures exactly how it behaves: large-eyed, secretive, and gone in a flash the moment a diver draws near.
