The only species of the genus which can be diagnosed from other species of Cyprinidae in Iberian Peninsula by having upturned mouth, dorsal origin behind pelvic fin base, scaleless keel between pelvic fin and anus, 58-73 total scales in midlateral row, incomplete lateral line with perforating 2-23 scales (sometimes absent) and 84-130 gill rakes (Ref. 59043).
Body shape (shape guide): elongated.
Adults inhabit small streams with swift current (often pools in summer) and pebble to rock bottom, usually without submerged vegetation (Ref. 59043). Reported to occur in lowland streams with a moderate current and abundant submerged plants. Pelagic filter feeders (Ref. 26100) . Food consists of filamentous algae and small invertebrate. They migrate upstream to spawn then returns to downstream areas at beginning of summer, where permanent water is retained throughout the year (Ref. 59043). Due to its threats such as habitat destruction and water pollution (Ref. 26100), a conservation project started under the EU-Life Nature program (Ref. 59043).
