Description
The Common Bleak is a slender, silvery freshwater fish native to European rivers and lakes. Known for its schooling behavior, it typically inhabits the upper water column, feeding on small invertebrates. While not a common aquarium fish, it can be kept in a cool-water community tank with appropriate tankmates.
