Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 16.0 cm SL male/unsexed; (Ref. 7247)
Adults inhabit rocky reefs, occurring in small to large aggregations (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).
