生物學特性     字彙 (例如 epibenthic)

Facultative air-breathing (Ref. 126274); Found in lakes and rivers (Ref. 56749). Occurs in estuaries and lower reaches but has also been observed in the upper reaches during the rainy season. Species is omnivorous with a tendency to opportunism (Ref. 46915).

棲息於河口與下游但是已經也被在上游在雨季的時候觀察。 種是雜食性的具有一個投機主義的趨向.(參考文獻 46915)
