The Nkwasi Point population

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

About the species

Tropheus polli is a rock-grazing cichlid endemic to a single stretch of Lake Tanganyika's central-eastern, Tanzanian shore, and one of the largest members of a genus better known for its many color races. It is also one of the more contested: some authorities treat it as a valid species, while Ad Konings folds the eastern populations into the older Tropheus annectens. Whatever name wins, this is a sedentary, algae-scraping reef fish that almost never leaves its few square meters of rock, and a notoriously demanding one in the aquarium.
