The orange chromide (Pseudetroplus maculatus ; more commonly Etroplus maculatus) is a species of cichlid fish that is endemic to freshwater and brackish streams, lagoons and estuaries in southern India and Sri Lanka.[3][4][5] It is also known as pallathi (Malayalam: പള്ളത്തി) in Malayalam. The species is popular with fishkeeping hobbyists, and is kept frequently in aquariums.[4][6] The species is part of the family Cichlidae and is included in subfamily Etroplinae. The orange chromide reaches a length of up to 8 cm (3.1 in).[5]

The species co-occurs throughout its range with the green chromide (Etroplus suratensis). Orange chromides prey on the eggs and larvae of the green chromide and also act as a "cleaner fish" removing parasites from the larger green chromides in a cleaning symbiosis.[4] The species also feeds on zooplankton and algae.[5]

Parental care

edit

Young orange chromides feed on mucous coating of their parents; this is essential for the small fry survival. During the feeding period, the parent fishes' mucous glands increase 34%.[7]
