The Otter Point population

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

About the species

Copadichromis mloto is a slender, silvery zooplankton-feeding cichlid endemic to Lake Malawi, one of the "utaka" that hang in open water and pick copepods from the column with a fast, telescoping mouth. It is one of the great puzzles of the lake's flock: described by T. D. Iles in 1960 from Nkhata Bay and then effectively lost to science, the name went almost six decades without a confidently identified specimen. A 2023 genomic study finally pinned it down, showing that the fish trawlers and fishermen had long been calling Copadichromis virginalis is, for the most part, Copadichromis mloto. That fishery hold over it is also its problem: this is the "true utaka" most heavily netted on the lake, and its numbers have fallen.
