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处普遍地栖息于,偏爱洪泛区湖的静止的水域，沼泽与浸水的洪泛区。 很少发现于主要的河峡道了。 主要吃塘鳢科鱼 Ophieleotris aporos 与大的甲壳动物例如 Macrobrachium 虾。 也使用壶罐，手执的钓丝鱼叉，手抄网，勺形网与其它捕捉。 母鱼达到 39.6 公分 SL 。 (参考文献 9162)
