The South East Arm population

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

About the species

Lethrinops gossei is a deep-water, sand- and mud-sifting haplochromine cichlid endemic to the southern reaches of Lake Malawi, described in 1973 by Warren Burgess and Herbert Axelrod and named for the Belgian ichthyologist Jean-Pierre Gosse. Unlike the shallow-shelf members of its genus, it lives well down the slope on soft bottoms at roughly 90 to 130 m, where it mines the sediment for buried invertebrates. It is one of the offshore Lethrinops more familiar from trawl catches than from the aquarium, and little is recorded of its life history beyond what the genus as a whole shares.
