About the species

Petrotilapia sp. "Fuscous" is an undescribed rock-scraping mbuna from the mid-western shore of Lake Malawi, recorded from the Maleri Islands group and nearby island reefs. Petrotilapia is the lake’s genus of dedicated algae scrapers — deep-bodied, heavily muscled fish with several rows of hooked, recurved teeth built to strip tough algal turf from wave-battered vertical rock. The genus is notoriously under-described: extreme sexual dichromatism and strong locality-based colour variation mean many populations are known only by trade names, of which this is one. "Fuscous" — Latin for dusky or dark brown — points to its colouration. It has no describing author, FishBase entry, or IUCN status.
