Prefers coralline areas (Ref. 30573). Migrates to specific sandy areas near outer reef edge to spawn in late afternoons during full moon. Feeds on small benthic organisms living on sandy bottoms (Ref. 3409, 48635). In Palau, migrates to specific sandy spots near the outer reef edge to spawn in late afternoons around full moon (Ref. 37816). Forms schools. Feeds on small invertebrates found in the sand. Marketed fresh (Ref. 12915).
