Found in shallow water and seaweed-covered reefs as well as on open, sandy areas (Ref. 5592). An opportunistic predator, this cryptic fish lies unseen on the reef top waiting for small fishes to pass by (Ref. 5592). Although the flesh is of excellent quality, it is not utilized commercially due to its venomous spines (Ref. 9341).
