Occurs in shallow muddy bottoms from the coastline to 75 m depth; also in brackish estuaries and hypersaline lagoons (Ref. 5217). Inhabit mainly coastal waters and tidelands, but abundant in waters very near the sea to a few meters elevation with wholly freshwater ichthyofauna (Ref. 36880). Feeds mainly on zooplankton and zoobenthos (Ref. 13196). Taken with beach nets (Ref. 5217).
Distinct pairing (Ref. 205). Oviparous (Ref. 101737). Females produce numerous eggs in multiple spawnings during a prolonged spawning period (Ref. 101737).
