About the species

Xenotilapia leptura is a slender, rock-grazing cichlid endemic to Lake Tanganyika, recognizable by its low-slung, downward-facing mouth built for scraping algae from stone. Unusually for its lineage, it is a vegetarian among mostly invertebrate-sifting relatives, and it is a biparental mouthbrooder in which both parents share the brood. Its name is a taxonomic moving target: described in the monotypic genus Asprotilapia, moved into Xenotilapia by some authors, and still listed as Asprotilapia leptura by the Catalog of Fishes and the IUCN.
