The Cape Nambeyeye population

Plecodus elaviae "Cape Nambeyeye" is the Cape Nambeyeye population of Plecodus elaviae, a geographic colour form from the Zambia coast of Lake Tanganyika in the southern part of the lake. It is the same species as Plecodus elaviae, distinguished by its collection locality and local coloration; aquarists keep and breed it as a discrete, provenance-labelled line.

About the species

Perissodus elaviae is a scale-eating cichlid endemic to Lake Tanganyika, a member of the small but biologically famous tribe Perissodini whose adults make their living tearing scales from the flanks of other fish. At up to about 13 in (12.5 in) it is the largest of the lepidophagous Tanganyikan cichlids, a schooling, open-water hunter rather than a rock-dweller. Described by the Belgian ichthyologist Max Poll in 1949 and now often placed in the genus Perissodus, it is rarely seen in the aquarium trade — and for good reason: a fish that eats only living scales is one of the hardest cichlids on Earth to feed in captivity.
