Breve descrizione
Chiavi di identificazione | Morfologia | Morfometria
Facultative air-breathing (Ref. 126274); Adults inhabit quiet pools and backwaters of creeks and small to large rivers, swamps, lakes and overflow areas of large streams. Often occur near vegetation and submerged logs. Feed on other fishes and insects. Spawning occurs over vegetation or other submerged objects (Ref. 10294).
