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.

There are currently 11 recognized species in this genus:[1]

In the aquarium
Pelvicachromis comprise part of the arbitrary group aquarists refer to as "dwarf cichlids". They are relatively peaceful cichlids which can be housed with other species in planted, heated tanks.
Pelvicachromis are cave-spawners and will lay their eggs in any cave-like structure such as a clay pot, PVC pipe, coconut shell, etc. The female will initiate the spawning, often displaying or vibrating in front of the male. The female will deposit 50–300 eggs in the cave and the pair will guard the eggs. The eggs hatch in 3–8 days and become free swimming in 5–10 days.
There are yellow, blue, red morphs found in the tropical fish hobby.
