Pelvicachromis

Pelvicachromis is a genus of small (5.5–12.5 cm or 2.2–4.9 in), brightly coloured cichlids from tropical West Africa and Central Africa. They typically inhabit soft, acidic water (pH 5.0 - 7.0).

All species form monogamous pairs and use caves as spawning sites. Most are easily spawned in captivity.
