Short description
Bestämningsnycklar | Morfologi | Morfometri
Taggstrålar i ryggfenan (totalt) : 2 - 3; Mjukstrålar i ryggfenan (totalt) : 6 - 7; Taggstrålar i analfenan: 2 - 3; Mjukstrålar i analfenan: 5 - 6. Presence of two black spots on caudal base, lower one sometimes weak (Ref. 59043).
Body shape (shape guide): elongated.
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
Könsmognad | Reproduktion | Lek | Ägg | Fecundity | Larver
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).
