Neolamprologus timidus "Ulwile Island" is the Ulwile Island population of Neolamprologus timidus, 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 Neolamprologus timidus, distinguished by its collection locality and local coloration; aquarists keep and breed it as a discrete, provenance-labelled line.

About the species

Neolamprologus timidus is a slender, dark-bodied Tanganyikan cichlid that spent decades hiding in plain sight, lumped together with its near-twin Neolamprologus furcifer until a 2014 study teased the two apart. Endemic to a roughly 100 km stretch of the Tanzanian coast, it lives pressed against the undersides of boulders and the back walls of deep caves, often hanging belly-to-rock with its head pointing down. Its name, Latin for "shy," captures exactly how it behaves: large-eyed, secretive, and gone in a flash the moment a diver draws near.
