Inhabits fringing vegetation of rivers and lakes, feeding on zooplankton, beetles and other insects (Ref. 28714). Often reported in West Africa under name of M. acutidens.
Affinities: most similar to M. acutidens, from which it differs in the presence of conical, monocuspid (vs multicuspid) inner dentary teeth, inner premaxillary and outer dentary with fewer cusps, and a slightly more slender body (Ref. 80290).
