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
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]
