Etymology: Galaxias: Greek, galaxias, ou = a kind of fish (Ref. 45335).
Eponymy: Robert Mackenzie Johnston (1843–1918) was a scientist and statistician and, according to the galaxias etymology, was “…the father of Tasmanian ichthyology, who paid considerable attention to the local Galaxiidae. [...] (Ref. 128868), visit book page.

Facultative air-breathing in the genus (Ref. 126274); Found in shelter of rocks and boulders in lacustrine habitats, also found in swamps and streams draining in and out of lakes (Ref. 44894). Adults occur in the rocky margin of Clarence Lagoon, its outlet stream and several tributaries that flow into the lake. Adults feed on benthic crustaceans while juveniles feed partly on planktonic crustaceans, and insects and their larvae (Ref. 30189, 44894). Very secretive species, darts for cover under boulders if disturbed. The entire life cycle (may live for up to four years) takes place in fresh water. Adults move into inlet streams to spawn in spring. The demersal eggs take about 2 months to hatch. Fry reside in open surface waters of the lake (Ref. 44894).
成魚出現在克拉倫潟湖的岩石的邊緣, 它的出口水流與流入湖中的一些支流。 成魚吃底棲的甲殼動物，而稚魚吃部分在浮游性甲殼動物 , 與昆蟲與他們的幼體上。 (參考文獻 30189) 非常躲躲藏藏的種, 為在大圓石下面的表面衝出如果擾亂的。
