The South East Arm population

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

About the species

Placidochromis elongatus is a small, slender haplochromine cichlid known only from the deep water of southern Lake Malawi, where it lives between roughly 80 and 220 feet (82–220 ft) down. Described in 2004 from trawl-caught specimens, it is one of the genus's "deep-water" species: a fish science met through a net rather than a mask, never gathered for the aquarium trade and almost unknown to hobbyists. Its story is less about the tank than about how much of a famous lake's diversity still lives out of sight.
