Description
The species occurs in the tropical Pacific Ocean from Bali to Australia and New Caledonia in a depth range from 5-60m, more common at oceanic islands than on continental reefs, max. length 20cm. The species forms plankton-feeding aggregations high about outer reef slopes with far more females than males. Because the red and low-energy light from the flash is filtered out after a short distance, the fishes that are further away appear significantly more blue.
