They are carnivorous, preying on smaller fishes, as well as benthic invertebrates. This species can reach a length of, though most only reach a length of around. This species is sought-after by local peoples for food and can also be found in the aquarium trade.
The two-lined monocle bream exhibits biofluorescence, that is, when illuminated by blue or ultraviolet light, it re-emits it as green, and appears differently than under white light illumination. Biofluorescence may assist in intraspecific communication and camouflage, blending the fish with green-fluorescing Acropora corals.
