Galaxias tantangara

Status: Critically Endangered on the EPBC Act list

Galaxias tantangara is a small fish in the family GALAXIIDAE, with a maximum recorded size of 110 mm (Length to Caudal Fork; LCF), and commonly to 75–85 mm LCF. It is a small fish with a distinctly stocky body. The body is predominantly dark olive to brown on the back becoming lighter brown to cream underneath.
