Maturity: Lm ?  range ? - ? cm
Max length : 4.1 cm SL male/unsexed; (Ref. 13227)
Adults are found in rock pools and the upper subtidal zone. Mostly associated with seagrass beds (Ref. 13227). Eggs are hemispherical and covered with numerous sticky threads that anchor them in the algae on the nesting sites (Ref. 240). Larvae are planktonic which occur primarily in shallow, nearshore waters (Ref. 94114).
