The Lyamembe population
Plecodus straeleni "Lyamembe" is the Lyamembe population of Plecodus straeleni, a geographic colour form from the Tanzania coast of Lake Tanganyika in the north-central part of the lake. It is the same species as Plecodus straeleni, distinguished by its collection locality and local coloration; aquarists keep and breed it as a discrete, provenance-labelled line.

About the species
Perissodus straeleni is a scale-eating cichlid endemic to Lake Tanganyika, one of a handful of fish on Earth that make a living tearing the scales off other living fish. Banded blue-and-black like the lake's big-headed Cyphotilapia, it has long been cast as a 'wolf in sheep's clothing' that mimics a harmless neighbor to slip within striking range of its prey. Modern DNA work on its gut contents has complicated that tidy story, showing it raids dozens of species rather than the one it supposedly imitates. Today the taxonomic authorities place it in the genus Perissodus, though the hobby and much of the literature still know it as Plecodus.
