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

Adults are secretive nocturnal fish that hide under ledges by day and come out only at night to feed on the epifauna of the substrate. The adults sometimes form large inactive aggregations in caves, but little or no feeding occurs. Schools of juveniles appear only in the summer.
