Facultative air-breathing in the genus (Ref. 126274); Inhabits stream margins over rock or sand bottoms, sometimes among aquatic vegetation. Still or gently flowing water on the margins of lakes, billabongs and streams. Usually swims in midwater over rock or sand bottoms, also in the vicinity of aquatic plants. Shoal forming (Ref. 44894). Feeds on a wide range of aquatic insects and crustaceans. Spawning has been recorded between August and September (Ref. 44894). Each spawning female releases 3,000-7,000 eggs which are slightly adhesive and settle to the bottom. Hatching in nine days at 9-14°C; newly hatched fry are 6-7 mm long.
棲息於在岩石或砂質底部上的水流邊緣, 有時在水生植物之中。 吃寬範圍的水生昆蟲與甲殼動物。 每個產卵雌性的釋放 3,000-7,000個卵那是些微聚集在一起而且對底部定居。 在 9-14 °C 在九天內孵化; 最近孵化魚苗是 6-7 mm 長。
