Inhabits estuaries and the lower reaches of coastal streams (Ref. 44894). Occurs in lowland streams, forming schools that feeds at or near the surface on insects and zooplankton. Found among the annual Tasmanian whitebait migrations in shoals with Lovettia seali and various galaxiids. Most of the life cycle is spent at the sea (Ref. 44894). The species is thought to have an anadromous life cycle involving upstream migration of adults from the sea prior to spawning. Newly hatched larvae are carried on tides out to sea where they develop to maturity (ref. 44894).
出現於低地的溪流, 形成群體那一個吃在或在昆蟲與浮游動物上的接近水表面。 此魚種被認為包括在產卵之前是距離海洋的成魚的溯溪迴游的具有一個溯河洄游產卵的生命周期。
