Facultative air-breathing in the genus (Ref. 126274); Commonly found throughout the lower altitudes of the Sepik River basin, preferring still waters of floodplain lakes, swamps and inundated floodplain. Rarely found in the main river channel. Feeds mainly on the eleotrid fish Ophieleotris aporos and large crustaceans such as Macrobrachium prawns. Also caught using pots, handlines harpoons, hand nets, scoop nets, and others. Female reaches 39.6 cm SL (Ref. 9162).
在 Sepik 河流域的下面高度各處普遍地棲息於,偏愛洪泛區湖的靜止的水域，沼澤與浸水的洪泛區。 很少發現於主要的河峽道了。 主要吃塘鱧科魚 Ophieleotris aporos 與大的甲殼動物例如 Macrobrachium 蝦。 也使用壺罐，手執的釣絲魚叉，手抄網，勺形網與其它捕捉。 母魚達到 39.6 公分 SL 。 (參考文獻 9162)
