Diagnosed from other species of Barbus and Luciobarbus in Iberian Peninsula by having the following characters: lateral line with 43-48 + 2-3 scales; last simple dorsal ray slender, not serrated posteriorly in adults, occasionally with a few small, widely set serrae in individuals smaller than about 15 cm SL; posterior barbel reaching beyond posterior margin of eye; lower lip thick, without median lobe; and lower jaw tip covered by lower lip (Ref. 59043).
Inhabits lower and middle reaches of rivers with slow current, preferring areas with vegetation and shore cover. Migrates upstream areas with faster current and gravel or stone bottom for spawning (Ref. 59043). Feeds on invertebrates and plants (Ref. 26100) and algae (Ref. 59043).
