Maturity: Lm ?  range ? - ? cm

Adults inhabit lagoon and outer reef environments at One Tree Island, GBR in Australia. Found solitarily or in small groups in open sandy or rubble areas with occasional coral outcrops. Feed primarily on algae (Ref. 7247). Oviparous, distinct pairing during breeding (Ref. 205). Eggs are demersal and adhere to the substrate (Ref. 205). Males guard and aerate the eggs (Ref. 205).
