Description synthétique
Clés d'identification | Morphologie | Morphométrie
Épines dorsales (Total) : 2 - 3; Rayons mous dorsaux (Total) : 6 - 7; Épines anales: 2 - 3; Rayons mous anaux: 5 - 6. Presence of two black spots on caudal base, lower one sometimes weak (Ref. 59043).
Adults are found from small lowland streams to large rivers with gentle current, and lakes mostly with dense vegetation on sand-silt to sand-gravel bottom (Ref. 59043). Oviparous, possibly with distinct pairing during breeding similar to congeners (Ref. 205).
Life cycle and mating behavior
Maturities | Reproduction | Spawnings | Egg(s) | Fecundities | Larves
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).
