The Otter Point population

Lethrinops lethrinus "Otter Point" is the Otter Point population of Lethrinops lethrinus, 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 lethrinus, distinguished by its collection locality and local coloration; aquarists keep and breed it as a discrete, provenance-labelled line.

About the species

Lethrinops lethrinus is the fish that gave a genus its name — the type species on which Charles Tate Regan founded Lethrinops in 1922, and from which the entire assemblage of Malawi's sand-sifting cichlids takes its identity. Endemic to Lake Malawi, Lake Malombe, and the upper Shire River system, it inhabits shallow sandy and muddy areas near river outlets, where it forages for buried invertebrates by scooping mouthfuls of substrate and straining them through the gill rakers. Breeding males are among the more peaceable of the lake's haplochromines, often holding colour side by side while competing for females over open sandy leks.
