Description

The sunbleak is a very small, slender freshwater fish of the family Cyprinidae reaching about 9 cm but usually smaller. The compressed body is translucent silver with a bluish sheen, an upturned mouth and a strikingly short, incomplete lateral line. The species lives in schools in still and slow-flowing, vegetation-rich ditches, pools and ponds of central and eastern Europe, often just below the surface. As an omnivore it eats zooplankton, small insects and algae. In spring the female lays the eggs in spiral strands on water plants, after which the male guards them. Through loss of small waters the sunbleak has declined locally; in the Netherlands it is a protected species.
