Biology     Glossary (e.g. epibenthic)

Adults occur in turbid estuaries, mangrove-lined lagoons and lower parts of rivers being very tolerant to changes in salinity. Found on shallow soft bottoms (Ref. 5217). Feed on a large variety of bottom-living and pelagic organisms including those found among the roots of mangroves. Reproduction occurs between September and December. A female lays 20-30 eggs, with a diameter of 10-12 mm. Males incubate the eggs in their mouth (Ref. 35381).

Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

Females reach maturity at a younger age than males and grow faster. The male incubates 28-40 eggs in the mouth and 200-400 eggs that are fixed in a glutinous mass on its head. Incubation takes 10-12 days. After 50-60 days fully functional young (6-6.5 cm TL) are released.
