About the species

Maylandia usisyae is a small, slender mbuna cichlid endemic to Lake Malawi, formally described in 2016 from a stretch of rocky shoreline near the village of Usisya on the lake's northwestern coast. Known to aquarists as the "Usisya" or "Yellow Mara Elongatus," it is an aufwuchs-comber of the intermediate zone where rock meets sand. Its standout fact is also its predicament: it is known from just two reefs totaling roughly 4 km², which is why the IUCN lists it as Critically Endangered even though it is locally common where it occurs.
