Feeds on tips of coral branches, gastropods, crustaceans, foraminifera, tunicates and sea urchins. Males establish territories with nest sites and egg chambers at traditional spawning grounds. Females select a male for mating. Up to 430,000 or more eggs may be deposited in a spongy fist-sized cluster weighted down with pieces of rubble. Nest-guarding females are aggressive.
