Biologi     Daftar kata (contoh epibenthic)

Facultative air-breathing in the genus (Ref. 126274); May penetrate some distance inland and is widespread in lakes and rivers (Ref. 3563), which may be either acid (pH 5-6,5) or alkaline (pH 8-9) (Ref. 93592, 93822). Prefers gentle currents within shelter of banks near the head of pools (Ref. 3563, 52193). Small but extremely hardy, they are known to tolerate a wide range of water and temperature conditions (Ref. 5214, 6164, 52193, 93591, 93592). Feeds on small drifting invertebrates (Ref. 7248, 52193). Spawning period occurs in spring up to middle of summer (Ref. 5214, 33843, 52193), depending on the conditions (Ref. 52193). Ripe eggs are demersal, relatively large and numbering about 30-40 (Ref. 93592). Their small size and cryptic color enable them to avoid predators (Ref. 52193).
