Description
The Thickhead Chub is a unique cool-water minnow native to the Pacific Northwest of North America. Known for its specialized mouth adapted for scraping algae and diatoms from surfaces, it is primarily herbivorous but will also consume aquatic insects. This hardy species can reach up to 12 inches and requires a large, well-oxygenated tank mimicking its natural riverine habitat.
