Description
The Chiselmouth is a unique North American cyprinid known for its distinctive cartilaginous lower jaw, which it uses to scrape algae and diatoms from rocks. This large, silvery fish, often displaying reddish-orange fins, inhabits cool, clear rivers and streams of the Pacific Northwest. It is primarily herbivorous and requires a spacious, well-oxygenated environment.
