Biologi     Ordlista (t.ex. epibenthic)

Inhabit sheltered rocky reefs (Ref. 48637). Also live in intertidal reef flats, lagoon and seaward reefs. Occur over open barren areas, also among corals and under ledges (Ref. 9710). Benthopelagic (Ref. 58302). Often found in pairs, sometimes in small groups. Feed mainly on filamentous red and green algae and coralline red algae but also on corals, tunicates, mollusks, echinoderms, polychaetes, crustaceans and bryozoans. Common (Ref. 9710). Monogamous (Ref. 52884).

Life cycle and mating behavior Maturities | Reproduktion | Spawnings | Egg(s) | Fecundities | Larver

Oviparous (Ref. 205). Displays facultative monogamy where males are constrained to mate with a single female due to resource limitation (Ref. 52884).
