Biologie     Fachlexikon (Englisch) (z.B. epibenthic)

Usually observed in pairs or small groups in rocky areas near the shore (Ref. 4858). Feed on algae and benthic invertebrates (Ref. 28023). Form schools with Chaetodipterus zonatus (Ref. 9286). Oviparous (Ref. 205). Form pairs during breeding (Ref. 205). Minimum depth reported from Ref. 5227.

Life cycle and mating behavior Geschlechtsreife | Fortpflanzung | Ablaichen | Eier | Fecundity | Larven

Form pairs during breeding (Ref. 205). Monogamous mating is observed as both obligate and social (Ref. 52884).
