Yellowish tan to yellow, 7 gray vertical bars on the upper body and rows of darks spots below, orange eye bar and a black spot on the nape. They usually live in pairs, and sometimes mingle with Chaetodon pelewensis, dot & dash butterflyfish, which looks very similar.
Least concern on the IUCN Red list. They rely on health, live corals, so decline of reef habitat could possibly threaten this species, as it would most butterflyfish, but the global population seems stable.
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. Common in coral rich areas and clear waters of lagoon and seaward reefs. Sometimes found on outer subtidal reef flats, in a depth range of 1-45 meters.
Often in pairs during breeding, monogamous and oviparous. Occasionally hybridize with Chaetodon pelewensis in the southern part of its range.
Up to 12cm.
They feed on coral polyps, filamentous algae and invertebrates.
