Care notes
Primitive SA cichlid related to Geophagus but more demanding. Requires very warm, soft acidic water with high flow. Sandy substrate for sifting essential. Rare in hobby — a specialist's fish.
Check the whole aquarium. Tank size alone does not establish compatibility. Confirm adult size, water overlap, social grouping, territory, diet, and the individual animals before stocking.
