A schooling species found inshore, but also inhabits deep bays under oceanic influence. Rarely enter mangrove waters (Ref. 43081). Probably feed mainly on planktonic crustaceans (e.g., copepods, Ref. 8591). Eggs are oval, without a knob at one end. Eggs occur intermittently in the lower reaches of mangrove waters (Ref. 43081). Utilized mostly for bait, but also for human consumption as dried fish or fermented sauce (Ref. 9987).
