Description

The Iberian roach or calandino is a small, slender cyprinid of the family Cyprinidae (Leuciscidae) reaching about 25 cm. The silvery-grey body often bears a dark lengthwise stripe along the flank. The species is scientifically famous as a hybridogenetic complex: it arose from hybridisation of several cyprinids and reproduces partly clonally, with populations made up of different combinations of parental genomes. It is endemic to the fresh water of the Iberian Peninsula and lives in schools in slow to moderately flowing rivers and streams. As an omnivore it eats insect larvae, small crustaceans, algae and plant material, and it tolerates warm, oxygen-poor summer conditions. Through its broad tolerance it is locally common and is assessed as Least Concern (LC).
