Body shape (shape guide): short and / or deep; Cross section: compressed.
Adults inhabit coral and rocky reefs (Ref. 7247). A protogynous hermaphrodite (Ref. 55367). Feeds on zooplanktons (Ref. 89972). 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).
Life cycle and mating behavior
بلوغ | تولید مثل | تخم ریزی | تخم ها | Fecundity | توزاد ( لارو)
Forms permanent harem groups composed of a single male and several smaller females (Ref. 55367). A monandric species (Ref. 55367). Oviparous (Ref. 205). Eggs are demersal and adhere to the substrate (Ref. 205). Males guard and aerate the eggs (Ref. 205). While protogyny was originally proposed for this species such as the report of length at sex change = 6.8 cm TL (Ref. 55367), recent studies confirmed gonochorism in the form of non-functional hermaphroditism (Ref. 103751).
