About the species

Iodotropheus sprengerae, the rusty cichlid, is a small rock-dwelling mbuna found only at a handful of islands and reefs in the southeastern arm of Lake Malawi. Drab at first glance, an adult male catches the light as a wash of rust-orange over lavender-blue flanks, and the species' even temperament has made it one of the gateway African cichlids for the hobby. It is also a biogeographic oddball: the sole widely accepted member of its genus, with a natural range you could circle on a map in a few square kilometers.
