The orange chromide (Pseudetroplus maculatus) is a species of cichlid endemic to freshwater and brackish streams, lagoons and estuaries of southern India and Sri Lanka.[3][4][5] It is popular with fishkeeping hobbyists,[4][6] and reaches a length of up to 8 cm (3.1 in).[5]

Names

[edit]

The specific epithet of this species, maculatus, is Latin for "spotted", and is a reference to the large black spot on the upper flanks. In Malayalam, it is known as pallathi (പള്ളത്തി).

Diet

[edit]
The selectively bred bright orange-yellow variant often seen in the aquarium trade

This species co-occurs throughout its range with the green chromide (Etroplus suratensis) and preys on the eggs and larvae of the latter. Additionally, it removes parasites from the larger green chromide; this is an example of cleaning symbiosis.[4] This species also feeds on zooplankton and algae.[5]

Parental care

[edit]

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