It is native to the waters of the western Pacific Ocean, near India, Indonesia, Philippines, New Guinea, and Australia. It prefers coral reefs and shallow lagoons. 

The Four Stripe Damselfish is omnivorous. It eats fish eggs, crab larvae, shrimp, algae, and small aquatic animals such as zooplankton.

It is seen in schools.

The male and female make a nest on the rocky or sandy sea floor. The female lays eggs in the nest and the male guards them. She lays between 6,000 and 73,000 eggs, but most of them are eaten by other fish.
