Description
The Arctic Grayling is a striking coldwater fish distinguished by its large, sail-like dorsal fin, which is often iridescent and spotted. Native to pristine arctic and subarctic rivers and lakes, it requires highly oxygenated, cool environments. This species is rarely kept in home aquariums due to its specialized care requirements and large size.
