Habitat and Ecology:

Inhabits shallow sandy, coral rubble, mangroves, lagoons and seagrass areas inshore and adjacent to coral reefs (depth 0-20 m). Utilizes seagrass beds as nursery grounds and 
as a larger adult begins to use reef habitat. Most often observed solitary but sometimes in small schools. Feeds on polychaetes, crustaceans, molluscs, echinoderms and small 
fish. Individuals have small, well-defined home ranges which are influenced by interspecific competition among similarly sized individuals, home range increases with body 
size. This species is considered a protogynous hermaphrodite.


Fishery Status:

This species is not protected or subject to fishery regulations. It is caught in the trap and handline fisheries, but is a quite rare component of the catch.
