Inhabits ponds, dune lakes and creeks, usually among aquatic weeds (Ref. 6398). Lives in swamps with prolific sedge growth, gently flowing streams and dune lakes in areas of coastal heathland (wallum). Water is often darkly tannin-stained and acidic (pH 5.4-6.5) with temperature range from 12° to 28°C (Ref. 44894). Feeds primarily on aquatic insects and their larvae (Ref. 5259). Also consumes microcrustaceans and algae. Breeding season extends from October to May, when water temperatures rise above 20°C. The breeding habits and biology are similar to other nannopercids, but this species takes only 4-5 months to attain sexual maturity (Ref. 44894). Aquarium conditions: pH=7.2, H=8, 26°C water temperature, egg layer, plant and rock cover, peaceful community fish (Ref. 6398).
