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.
