Description

The Madagascar coastal cichlid is a cichlid endemic to eastern Madagascar. The species grows to about 30 cm and has a deep, laterally compressed, greyish to red-brown body, often with a red tinge on the fins. Unlike most Paretroplus species it tolerates brackish water and occurs in the lower reaches of rivers, lagoons and estuaries on the east coast. As an omnivore it feeds on molluscs, small invertebrates, plant matter and detritus. Cichlids form pairs and guard their eggs. Owing to habitat loss the species is listed as Vulnerable (VU); Madagascan cichlids are an ancient, threatened group. The species is a local food fish and is harmless to humans.
