📖 Overview

Inhabits lagoons and along shorelines of outlying islands . During daylight, schooling fish may be periodically seen to jump out of the water to avoid predators. They are also easily attracted to light. The fish are gravid at about 4-4.5 cm SL by July in the northern hemisphere. Because of their large numbers, they are probably important as forage food for larger fishes .
