Description
The Mountain Whitefish is a slender, silvery freshwater fish native to cold, clear rivers and lakes of western North America. It possesses a small, subterminal mouth and an adipose fin, characteristic of the Salmonidae family. While primarily a sport fish, its specific cold water and environmental needs make it unsuitable for most home aquariums.
