The Chemwezi Rocks population

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

About the species

Corematodus taeniatus is one of only two known species in Corematodus, a small genus of Lake Malawi haplochromine cichlids built around an unusual and precise diet: the scales of other fish. Its slender, silvery body is shaped to blend into passing schools of small plankton-feeding cichlids, a disguise it uses to slip in close before rasping scales from a victim's flank with specialised teeth. It shares this scale-eating (lepidophagous) strategy with its congener Corematodus shiranus and, more distantly, with the fin-biting Docimodus of the same lake — part of a small guild of Malawi cichlids that crop tissue from other fish rather than killing them outright.
