More about the species
Description
This schooling species occurs along sandy and rocky shorelines and over sandy lagoon bottoms, often in zones of turbulence. Benthopelagic. Often encountered in river mouths or brackish mangrove estuaries. Feeds mainly on crustaceans (shrimps and crabs), polychaete worms, other benthic invertebrates; also on teleosts. A lunar spawning rhythm occurs close to shore. Sexual maturity in males occurs at 12 to 15 cm. Subsequently undergoes sex reversal passing through a hermaphroditic stage, and become female between 18 and 24 cm. The potential of this species for aquaculture has been studied.
