Description
The Guadalupe Darter is a small, slender freshwater fish endemic to the Guadalupe River system in Texas. It typically displays cryptic coloration with mottled brown and olive patterns, allowing it to blend into rocky and gravel substrates. These active bottom-dwellers require clean, well-oxygenated water with good flow.
