Description

The eastern mudminnow is a small, hardy freshwater fish of the family Umbridae reaching about 14 cm. The stout, brownish body bears several narrow, dark longitudinal stripes and a rounded tail. The species is native to the eastern United States but has been introduced to Europe and locally established, including in Dutch and Belgian moorland pools, ditches and marshes. It is extraordinarily tolerant of oxygen-poor, warm and acidic water and can gulp air with its swim bladder to survive. It hunts small aquatic insects, crustaceans and worms. In spring the female guards the eggs in a nest among water plants. Through its hardiness it can displace native species.
