Galaxiella toourtkoourt, known as the little galaxias (although it is not a true member of the genus Galaxias), is a species of fish in the family Galaxiidae. It is among the smallest galaxiid species known. It is a freshwater fish native to Australia, where it ranges from the Barwon River basin near Barwon Downs in Victoria west to the Watervalley Wetlands near Coorong National Park in South Australia. It is typically seen in swamps, wetlands, billabongs, shallow lakes, small streams, and artificial drainage systems in water less than 2 m (6.6 ft) deep and at elevations of between 22 and 176 m (72 and 577 ft) above sea level. The environments in which the species occurs are usually characterized by still or slow-flowing water and partial shade, and they may occasionally be slightly saline.
