Indo-Pacific: East Africa to Tuamoto Islands, north to the Ryukyu Islands, south to Sydney, Australia, including Lord Howe Island.
Common in clear outer lagoon and seaward reefs, over hard bottoms as well as over sand and rubble. Typical along reef-crests in depths of 1-6 m, but has also been collected from depths of 24 m. Usually seen in pairs, hovering near their burrow. Monogamous (Ref. 52884, 48637). Feeds on small benthic invertebrates, fishes, and fish eggs by sifting mouthfuls of sand.
