Biology

Inhabits lagoons and along shorelines of outlying islands (Ref. 3302). 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 (Ref. 9760).
