Common Dace Leuciscus leuciscus

The Dace, called Common Dace to distinguish from other species, is native to rivers and streams of Europe and northern Asia but has been introduced elsewhere. Like a slender Roach without the red eyes, a slender Barbel with triangular anal fin and without barbels (above right with a Barbel), a slender Chub with a more forked tail or, on continental Europe, similar to a Nase but the Dace, another member of the Carp family, has a longer top mandible and a shorter lower mandible than all these, giving a lower mouth. It can grow to 30cm (a foot) long.
