Comments: Most specimens  of this 'twilight zone' species are reported from the 70 m depth range (though
  have been collected as shallow as 45-55 m in the Lembeh Strait).  The species do not appear to school or aggregate as with many congeners, but rather are found individually in small caves and crevices, frequently quite deep into the interstices of the reef and only visible using a strong underwater flashlight.  Specimens collected were found exclusively on deep reefs sheltered from wave exposure but nonetheless exposed to currents, and although there was frequently significant silt build-up present in the caves in which they sheltered, water visibility was always good because of the significant water flow over the reefs (Ref. 96671).
