Indo-Pacific: Christmas Island in the eastern Indian Ocean to the Line Islands, north to the Ryukyu Islands, south to Rowley Shoals and the northern Great Barrier Reef; throughout Micronesia. Replaced by Chaetodon guttatissimus in the Indian Ocean (Ref. 37816).
Common in coral rich areas and clear waters of lagoon and seaward reefs. Sometimes found on outer subtidal reef flats (Ref. 1602). Juveniles secretive (Ref. 48636). Feed on filamentous algae, corals, and benthic invertebrates. Often in pairs during breeding (Ref. 205), monogamous (Ref. 52884). Oviparous (Ref. 205).
