This loach has a very wide range, especially in Europe. It occurs north of the Alps, from the Meuse River in western Europe all the way to the Neva River in northwestern Russia. It also occurs in the northern part of the Black Sea basin from the Danube River to the Kuban River, and in the Caspian Sea in the River Volga and River Ural drainages. It is also introduced in a few different areas, but not to the extent of the pond loach (Misgurnus anguillicaudatus).
Adult weatherfish live in dense patches of aquatic vegetation while juveniles prefer to live near the shoreline in very shallow water where there is a lot of detritus; neither adults nor juveniles are found in open areas without vegetation. Because of their habitat preferences, dredging and aquatic weed removal poses a danger to weatherfish populations. The weatherfish is listed as least concern but is protected in most of its range. They are able to survive in habitats that many other fish would be unable to because of their ability to breathe atmospheric oxygen. In low oxygen conditions, the weatherfish will swim to the surface and gulp air. The air then goes through the intestines where a complex system of blood vessels extracts the oxygen, before expelling the air from the anus.
