The South East Arm population

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

About the species

Otopharynx speciosus is one of the lake's many non-mbuna haplochromines that patrol the intermediate zone where scattered rock gives way to open sand — a habitat niche the genus Otopharynx has diversified into repeatedly across Lake Malawi. The species epithet, Latin for "showy" or "beautiful," points to the bright breeding dress of territorial males, the usual signal in this genus that separates a plain, silvery non-breeding fish from a fish in full display. It is documented from Nkhomo Reef on the western shore and from the South East Arm, a spread that suggests a wider lakewide distribution rather than a narrow single-reef endemic.
