About the species

Pseudotropheus fuscus is a rock-dwelling mbuna from the northern shore of Lake Malawi, its Latin name — "dusky" or "dark brown" — describing a comparatively subdued coloration that sets it apart from the vivid blues and yellows of many showier mbuna sharing its rocky habitat. It belongs to Pseudotropheus proper, one of several genera carved from the historic catch-all group of small, barred Lake Malawi rock cichlids.
