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. The species also feeds on zooplankton and algae.

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%.{{cite book|last1=Gerking|first1=Shelby D.|title=Feeding Ecology of Fish|date=Apr 25, 2014|publisher=Elsevier|page=286|isbn=9781483288529}}
