A relatively rare species occurring singly but usually in pairs over silty flat sand patches, or rubble substrates; a mound-building species. Usually found on outer reefs at the bottom of coral or rocky drop-offs, rarely in lagoons. Feeds on small burrowing animals by sifting mouthfuls of sand. Monogamous (Ref. 34105, 48637, 52884). Eggs hatched 2 days after spawning in aquaria; 35 days after, the larvae reached 5.25 mm.
