The Nkhomo Reef population

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

About the species

Copadichromis azureus, the blue utaka or electric-blue Copadichromis, is a zooplankton-feeding cichlid endemic to the southern half of Lake Malawi. Females and juveniles wear the drab silvery-beige livery typical of the genus, marked with three dark spots along the flank, but a dominant male in breeding dress transforms into one of the most intensely coloured fish in the lake: a deep, metallic azure that gives the species both its epithet and its hobby fame. It belongs to the utaka, the open-water plankton-pickers of Malawi, yet it stays closer to the bottom than most of its relatives, hovering over the sand-and-rock interface where the males build and defend sand-bowl bowers.
