Occurs inshore and forms quite large schools. Enters brackish waters of lagoons and estuaries and can tolerate salinities of 10.32-31 ppt (Santa Cruz Canal, Pernambuco, Brazil). A filter-feeder presumably on both phytoplankton and zooplankton. Spawns off the Araya Peninsula, Venezuela from October to January, with a distinct peak in mid-November. Eggs are oval, spawned at 0230-0500 hours along shoreline out to about 1.5 km and hatching at about 20-24 hours later.
