Africa: Endemic to Lake Malawi. Previously, two subspecies were recognized: Protomelas marginatus marginatus (southern end of the lake) and Protomelas marginatus vuae (northern end of the lake).
Inhabits shallow vegetated areas. Feeds on algae and debris of vascular plants. Ingestion of small invertebrates is possibly incidental (Ref. 267).
