The whitespotted surgeonfish is found in shallow water in the Indo-Pacific. Its native range extends from Mauritius to southern Japan, Indonesia and northern Australia but in 2003, it was observed off the coast of Florida in the vicinity of Palm Beach. Its main habitat is exposed reefs and rocky shores where it occurs in groups. Its spots may provide camouflage in the churned up, bubble-filled water.
