Biology:  A short-lived species (less than 2 years) which inhabits shallow, well vegetated habitats - streams, lakes, estuaries, lagoons, lower reaches of rivers, springs and brooks. Feeds on invertebrates. Spawns after first winter in April-August.; females may spawn every 10-15 days during the season. Males defend eggs in cavities under stones, plant material or shells; may overturn and clean suitable shells for spawning and these are then covered with substrate.
