Lives in streams, backwaters, lakes, swamps and estuaries. Occurs in brackish estuaries and inland salt lakes. Most common in slow-flowing streams and still waters, shoaling near the surface or around the cover of aquatic plants and woody debris. Forms large aggregations in open water (Ref. 44894). Feeds on aquatic insects, microcrustaceans and algae. Spawns throughout the Murray-Darling river system. Breeds between July and March (mostly in spring) (Ref. 44894). Spawning temperature is about 15 °C. Newly hatched larvae measure 4.8 mm TL on the average. Eggs are laid among aquatic vegetation and hatch in about 10 days. Sexual maturity is attained by the end of the first year (Ref. 44894). Eaten fresh or canned.

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.6406 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Trophic level (Ref. 69278): 2.8 ±0.29 se; based on food items.

Generation time: 3.6 ( na - na) years. Estimated as median ln(3)/K based on 2 growth studies.

Resilienza (Ref. 120179): Alto, tempo minimo di raddoppiamento della popolazione meno di 15 mesi (K=0.31; tm=1; tmax=2).

Fishing Vulnerability (Ref. 59153): Low vulnerability (13 of 100).

Price category (Ref. 80766): Unknown.
