Breve descrizione
Chiavi di identificazione | Morfologia | Morfometria
Lamina circularis absent. Body depth is 9-11% of SL. Dorsal origin behind or above pelvic origin.
Body shape (shape guide): elongated.
A short-lived species which inhabits upper and middle reaches of rivers, with shallow waters and stony bottom (Ref. 11240). Adults feed mainly on aquatic invertebrates (Ref. 59043). Oviparous, with distinct pairing during breeding (Ref. 205). Maturity is reached at 1 yr of age (Ref. 59043). Are hreatened due to pollution, habitat destruction and the introduction of other species (Ref. 26100, 59043).
During courtship, 'the male follows the female and, after both enter dense vegetation (e.g. filamentous algae), the male forms a complete ring around the female's body behind the dorsal as the female releases the eggs' (Ref. 59043).
