About the species
Tropheops microstoma is a small, intensely sky-blue mbuna found only in Lake Malawi, where it grazes algae from the seam between rock and sand around a single stretch of shoreline on the Nankumba Peninsula. Its species name means "small mouth," a nod to the narrow, blunt jaws that mark it as one of the more specialized members of a notoriously hard-to-pin-down genus. Beautiful and territorial in equal measure, it is a fish that rewards space and punishes crowding.
