A member of the family Cichlidae, it can grow up to 22.5 cm (8.9 in) in standard length.[1] It is benthophagous by nature, taking mouthfuls of substrate (hence its common name) and sifting for edible items, with the remaining materials being expelled via the mouth and gill openings. It prefers clear and blackwater environments as opposed to turbid white waters.[3]
