Adults occur singly or in small groups. Juveniles occur singly.
Feeds on invertebrates.
In Indonesia, the species is reported to form groups to blow water jets towards an ambushing predator, the Bobbit worm (Eunice aphroditois), which preys on the species. This behaviour may benefit other individuals of the Peters’ monocle bream by exposing or even deterring Bobbit worms.
