Biologi     Ordlista (t.ex. epibenthic)

Facultative air-breathing (Ref. 126274); Adults occur in sluggish pools, backwaters and oxbows of medium to large rivers, and lakes (Ref. 10294). Usually found near vegetation. Occasionally found in brackish waters. Spawning occur in freshwater and possibly slightly brackish water (Ref. 4639). Migrate up rivers during the spawning season (Ref. 4639). Eggs and larvae are demersal and adhesive (Ref. 4639). Voracious predator, feeding on various fishes and crustaceans. The roe is poisonous.
