| 意見 | Found over rocky substrates and sandy area with algal growth. Gregarious, sometimes forming sizeable schools. Young mainly carnivorous on crustaceans, adults almost exclusively herbivorous (Ref. 4781), feeds on seaweeds (Ref. 36731). The Rhodophyta seem to be the most important component in the diet (59.6%), followed by Phaeophyta (24.8%) and Chlorophyta (15.8%) (Ref. 41885). |
