Description
The Tonguetied Minnow is a cool-water North American species known for its distinctive lower jaw, where the tongue is fused to the floor of the mouth. They inhabit clear, rocky streams and feed primarily on benthic invertebrates. This species is best suited for native or species-specific aquariums due to its specific environmental needs.
