Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 30.0 cm SL male/unsexed; (Ref. 7247); max. published weight: 379.00 g (Ref. 53696)
Adults inhabit rocky coasts (Ref. 9334). Feed on benthic algae and invertebrates (Ref. 28023). 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).
