The species reaches about 15 cm and has a deep, strongly compressed, copper-coloured body with large eyes and an upturned mouth. By day the fish gathers in dense schools in dark crevices, caves and under ledges in clear water with coral bottom; at night it swarms out to feed on zooplankton, especially invertebrate larvae. The juveniles are so transparent that the backbone can be seen through the body.
