Facultative air-breathing in the genus (Ref. 126274); Live in rocky shores, among aquatic vegetation, inundated terrestrial scrub and debris. Cryptic. They are benthic, preferring rocky lake margins in shallow water, but also occur to at least 10 meters depth. Found in swampy areas bordering lakes during floods. Remain close to available cover (rocks, wood, plants). Behave like a gudgeon, remaining motionless on the bottom most of the time and darting after prey with rapid bursts. They adopt the typical gudgeon posture of supporting itself with the pectoral fins (Ref. 44894). Feed on a variety of insects, microcrustaceans, worms, galaxiid eggs and algae. Spawn in spring; sexual maturity is reached after one year, maximum life span is two years (Ref. 44894).
生活在岩岸,在水生植物, 浸水的陆栖用力擦洗与残砾之中。 善于隐藏的。 一个底栖的鱼, 在浅水区中偏爱湖边岩石, 也出现到至少 10 公尺深度。 发现于在洪水的时候毗邻湖的沼泽的区域了。 逗留在接近有用的表面 (岩石，木材植物) 。 行为像一个白杨鱼, 在底部上保持不动大部分的时间而且冲出在用迅速的冲撞猎物之后。 它用胸鳍采用支撑的典型白杨鱼姿势它本身。 (参考文献 44894) 吃多种昆虫，小型甲壳类动物，蠕虫，南乳鱼科鱼类卵与藻类。 产卵在春天; 性成熟在一年之后被达成, 最大的寿命是二年。 (參考文獻 44894)
