Cryptic species between rocks near shore (Ref. 35773). Occurs in the upper 2-3 m of the water column (Ref. 7343, 46829, 52921). Feeds by scraping loose algae from the vertical faces of boulders in turbulent water (Ref. 6770, 46829). In order to cope with the movement of the surge its feeding speed is fast; very shy species; males are territorial and hide in large caves when threatened (Ref. 46829). Often solitary but more than 2 individuals may be seen at once (Ref. 7343).
