Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 9.0 cm TL male/unsexed; (Ref. 48636)
An ubiquitous species found in lagoons, coastal reefs, passages and outer reef slopes. Inhabits sandy areas around coral or rock outcrops or other protective shelter. Adults are usually in small groups (Ref. 48636). Feed primarily on algae, but also takes zooplankton. 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). Have been reared in captivity (Ref. 35404.
