Max length : 12.0 cm SL male/unsexed; (Ref. 44894); common length : 9.0 cm SL male/unsexed; (Ref. 5259)
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.
