Biologi     Ordlista (t.ex. epibenthic)

Occurs in shallow lagoons and seaward reefs to a depth of about 15 m; common in coral-rich areas. Secretive species (Ref. 9710, 48637) among rocks, sponges or in crevices on the bases of large coral formations. Adults usually form pairs but often only one is observed while the other one is hiding (Ref. 48637).
