Feeds on small invertebrates and (rarely) plants. Maximum size of about 27 cm SL.

Barbus meridionalis graellsii found in southern France and central and northern Spain is now recognized as species. The Italian populations now recognized as Barbus caninus. Morphology Dorsal spines (total): 3 - 4; Dorsal soft rays (total): 7-9; Anal spines: 2-3; Anal soft rays: 5 - 6; Vertebrae: 34 - 35.
