Euryhaline and mostly inhabits coastal floodplains where it’s found in both fresh and brackish habitats, including tidal estuaries and salt marshes. It’s particularly common in swamps, billabongs, and slow-moving streams where aquatic vegetation grows densely, but some populations have colonised upper sections of freshwater streams. Larger individuals may also move into main river channels.

Tappin (2010) gives the following ranges of parameters based on those taken from various localities: temperature 27 – 38 °C, pH 5…

Euryhaline and thus capable of withstanding significant fluctuations in salinity and other water conditions. It’s been recorded in full marine conditions as well as pure freshwater environments, and commonly inhabits coastal mangrove creeks and swamps.

Such changes may occur on a daily or seasonal basis depending on locality, with some habitats influenced by daily tides whereas others become hypersal…
