Description

The tonguetied minnow is a cyprinid from the eastern United States. The species grows to about 16 cm and has a stocky, brownish body. Characteristic of the genus is the peculiar lower jaw, whose central part is shaped like a bony 'tongue', to which the name 'tonguetied minnow' refers. It inhabits rocky pools and runs of clear creeks and small to medium rivers. As a bottom searcher it scrapes and picks growth, insect larvae, snails and small invertebrates from stones. The males build a conspicuous mound nest of pebbles for the eggs. The species is harmless to humans.
