Comments: Occurs in clear water with coral bottom.  Form aggregations in dark crevices and caves (Ref. 9710).  Nocturnal (Ref. 9626).  Its name probably refers to the juveniles, which are so transparent that the backbone can be seen in the living fish (Ref. 26938).  Feeds on zooplankton, particularly the larval stages of invertebrates (Ref. 13442).
