It inhabits a variety of freshwater environments, ranging from acidic swamps to rivers made of snow runoff, and is broadly distributed throughout the Northern Hemisphere and South Africa. The species has been subject of biological research since the 18th century. It is widely used in ecological and evolutionary studies, and in ecotoxicology. It is a popular fish food in aquaculture and aquaria.
