Description

The lake minnow is a small cyprinid with a wide range extending from Central Europe through Siberia to East Asia. The species reaches about 12 cm and has a stocky, brown-gold body with a mottled pattern. It inhabits densely vegetated, often oxygen-poor swamps, bog pools, ditches and small ponds, where it lives in schools. As an omnivore the fish feeds on zooplankton, insect larvae, algae and plant matter. In parts of Western Europe the species has become rare through loss of marsh habitat and is locally legally protected, although globally it is considered not threatened.
