This species is distinguished from its congeners by the following characters: no posterior oculoscapular canal; anterior extremity of anterior oculoscapular canal in front of middle of eye; body of live breeding males with dark spots or bars; back unscaled in front of ray 4-8 of second dorsal; total scales in midlateral series 32-39 (Ref. 59043).
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. Postlarvae are pelagic (Ref. 59043).
Eggs are found on undersurface of Cerastoderma valves (Ref. 4696). A multiple spawner, with 10-15 day cycle during the breeding season (Ref. 4696).
