The Blue Runner is a pelagic species which forms schools primarily inshore; it is not generally common around reefs. It has a depth range of 0-100 m and juveniles are found beneath floating Sargassum mats. These mats provide this species both with prey and protection from predators. It feeds on shrimps, fishes and other invertebrates.
Two spawning peaks have been identified for this species, the main occurring in June, July and August, with a secondary peak in October. However, it has also been suggested that spawning occurs throughout the year.
