توصيف مختصر كليدهاي شناسايي | ريخت شناسي | ريخت ستجي بوسيله انداره گيري

خارهاي باله پشتي (کل) : 3; شعاع نرم باله پشتي (کل) : 23 - 26; خارهاي باله مخرجي: 0; شعاع نرم باله مخرجي: 21 - 23.

Commonly found in subtidal reef flats and shallow protected lagoons, Ref. 48637. Benthopelagic (Ref. 58302). Juveniles secretive with rubble patches, adults swim about openly but are usually shy (Ref. 48637). Territorial. Feed on algae, detritus, mollusks, crustaceans, worms, sea urchins, fishes, corals, tunicates, forams, and eggs (Ref. 3921). Oviparous (Ref. 205). Sleep on its side; makes a whirring noise when alarmed (Ref. 4420). Also caught with drive-in nets and is considered a popular aquarium fish (Ref. 9770).

Life cycle and mating behavior Maturities | تولید مثل | Spawnings | Egg(s) | Fecundities | توزاد ( لارو)

Distinct pairing (Ref. 205). Mating system may be a mixture of polygyny, monogamy, and potential promiscuity in solitary females but the primary mating system considered for this species is polygyny (Ref. 116439). Females are territorial, solely tending and guarding the eggs (Ref. 116451). Males exhibit polygyny (Ref. 116451).
