The Border population

Copadichromis verduyni "Border" is the Border population of Copadichromis verduyni, 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 verduyni, distinguished by its collection locality and local coloration; aquarists keep and breed it as a discrete, provenance-labelled line.

About the species

Copadichromis verduyni is a small, deep-living utaka cichlid endemic to Lake Malawi, hovering in shoals over the eastern shore where sand meets rock. It belongs to the lake's guild of open-water zooplankton pickers, but it is the most secretive spawner among its kind: territorial males retreat to depths of 9 to 15 m (30 to 49 ft) and tuck their breeding burrows into small caves and crevices, the most cryptic nest sites of any Copadichromis. Named for the Dutch cichlid dealer Dirk Verduyn, the species shows a string of named colour variants around the lake and is currently assessed as Vulnerable.
