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:
