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

About the species
Boulengerochromis microlepis, the emperor cichlid of Lake Tanganyika, is widely regarded as the largest cichlid on Earth, reaching at least 32 inches (80 cm) and around 10 pounds (4.5 kg). It is the sole member of its tribe — a benthopelagic top predator that hunts the lake's open-water sardines and sand-dwelling fishes, then channels everything it has into a single, enormous brood of young. Many biologists believe it breeds only once and dies of exhaustion guarding its fry, a 'big-bang' life history almost unique among cichlids, though the claim is more debated than it first appears.
