Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 10.0 cm FL male/unsexed; (Ref. 5525)
Comprises several color forms, or geographical variations (Ref. 48636). Adults are found in mixed coral and rubble areas of lagoon and seaward reefs from the lower surge zone to a depth of 40 m (Ref. 1602). Solitary (Ref. 37816). Feed on filamentous algae and small invertebrates (Ref. 1602). 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). Diurnal species (Ref. 54980; 113699).
