The Border population

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

About the species

Lethrinops microstoma is a sand-dwelling haplochromine cichlid endemic to Lake Malawi, named for its distinctively small mouth — a build suited to fine-grained sifting of the finest particles from the sandy lake floor rather than to seizing larger prey. It is documented here from two widely separated sites, Border in the south and Manda in the north, hinting at a population that may range across a considerable stretch of the lake's sandy shore.
