Kurzbeschreibung
Bestimmungsschlüssel | Morphologie | Morphometrie
Lamina circularis absent. Body depth is 9-11% of SL. Dorsal origin behind or above pelvic origin.
A short-lived species which inhabits upper and middle reaches of rivers, with shallow waters and stony bottom (Ref. 11240). Feeds mainly on aquatic invertebrates (Ref. 59043). Oviparous, with distinct pairing during breeding (Ref. 205). Matures at 1 yr of age (Ref. 59043). Is threatened 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).
