The Mtoto population

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

About the species

Neolamprologus petricola is a rock-dwelling cichlid endemic to Lake Tanganyika, described by Max Poll in 1949 from M'Toto Bay on the lake's western shore. A stocky, cream-to-brown lamprologine of around 5 in (12-14 cm), it is one of the lake's many cave-spawning rock specialists — and one of its taxonomic puzzles, since at least one authority folds it into the closely similar Neolamprologus modestus. It reaches the aquarium trade only sporadically, but it offers a clean window into how Tanganyika's rocky littoral works.
