Misgurnus anguillicaudatus (Oriental Weatherfish) is native to fresh waters of East Asia, from Sakhalin Island, and the Amur and Tugur Rivers, south through Japan, Korea, and Taiwan, to Taiwan, Vietnam, and Burma (Lever 1996). This fish is common in the aquarium trade. Many local populations are established in North America, the Philippines, Hawaii, and Australia, Belgium, Germany, Spain, and Portugal (Lever 1996; Freyhof and Korte 2005; Franch et al. 2008; Van Kessel et al. 2013). In the United States, releases are known from 17 US states. The first reported US population was in the Shiawassee River headwaters, near Saginaw Bay, Michigan in 1939 (Mills et al. 1993). Estuarine populations are found in freshwater tributaries of the Columbia River, near Portland, in Tampa Bay, and along the Hudson River. The Oriental Weatherfish is most usually found in small streams or wetlands, silty backwaters, and rarely in large, deep bodies of water. It is tolerant of anoxia and turbidity, and can breath air (Wells 2014; Schmidt and Schmidt 2014). It can reach 280 mm, but is more usually 100-200 mm. Aquariists know the Oriental Weatherfish, as a slender, squirmy, eel-like fish and an escape artist.
