This species may not be taken without a permit, unless captured by the use of a bush pole. A bush pole is defined as a length of wood that is not less than one metre in length and does not have a reel and running line. Juveniles are often found in whitebait runs, for which there is a restricted recreational season requiring a Whitebait Licence.

Small elongated fish that have a single soft-rayed dorsal fin on their back. There are no scales present, but they do have a lateral line. The anal fin origin begins behind the dorsal fin origin. They have large pectoral and pelvic fins.

Colour and pattern variation is common, ranging from bold bands to irregular patches and blotches. Generally they are medium to dark brown with a lighter background and belly. Gold iridescence is often apparent on the back and sides.

Commonly from 80 to 160 mm, but up to 270 mm 

Native to Tasmania and also south-east Australia and New Zealand. It is the most widespread of the Tasmanian galaxias. It has both riverine and landlocked populations, and the juvenile especially is noted for its climbing ability using its large pectoral and pelvic fins. Consequently it is often found in the upper reaches of streams, past barriers blocking other fishes upstream movements. It is also the largest of the Tasmanian galaxias.

In riverine populations spawning takes place in autumn, although little study has been done, this is probably near their normal habitat. The larvae are swept to sea and return 5-6 months latter as part of the whitebait run in spring. Landlocked populations breed in spring.

Adult fish are secretive and solitary, and are rarely seen in the lower reaches of the rivers. They tend to inhabit the headwaters of clear bouldery streams with riffles and cascades, where they can be found under stones. Juveniles can be found in large schools around lake margins and near mouths of tributaries, where they are a food source for trout.

Carnivores feeding on a wide range of invertebrates, but also including some terrestrial insects taken from the water surface.

Widespread in coastal drainages as well as numerous landlocked populations in inland lakes
