More Info


Distribution

Usually solitary over sand or sand-and-rubble substrates near sheltered coral reefs at depths of 1–20 or 30 m. Juveniles are secretive, and often shelter near long-spined sea urchins.

Feeding

Feed by taking a mouthful of sand and detritus, and releasing the sand via the gill opening while sorting prey items in the mouth and pharynx. Larger sandy/coral fragments are ejected from the mouth. They Fiveband Wrasse also consumes larger benthic prey.
