Korte beschrijving
Determinatiesleutels | Morfologie | Morfometrie
Presence of mandibular barbel 4-8 times in HL. Pectoral fin length 4.3-5.4 times in SL in males, 4.3-9.0 times in females. 6-7.5 branched dorsal rays. One lamina circularis.
A short-lived species, secretive in nature (Ref. 38442). Adults inhabit middle and lower reaches, with shallow waters, sandy bottoms and submerged plants (Ref. 11240). During dry periods, they can survive in very small water bodies (Ref. 59043). Feed on invertebrates and plants. Spawn in May to July. Oviparous, with distinct pairing during breeding (Ref. 205). Eggs are small (1.7 mm) and sticky, placed within dense vegetation if available (Ref. 59043). Threatened due to pollution, habitat destruction and the introduction of other species (Ref. 26100).
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).
