Description
The Flannelmouth Sucker is a large, native North American freshwater fish characterized by its large, fleshy lips adapted for scraping algae and detritus from river bottoms. It is typically yellowish-brown to olive-green with lighter undersides. This species is found in the Colorado River basin and requires cool, clear, flowing water, making it unsuitable for most home aquariums.
