Juveniles on algae reef (Ref. 48637). Benthopelagic (Ref. 58302). Feed on algae, detritus, mollusks, crustaceans, worms, echinoderms, fishes, sponges, foraminiferans, and eggs. Territorial. Oviparous (Ref. 205). Also taken by drive-in nets (Ref. 9770). Minimum depth reported taken from Ref. 128797.
