Morphology | Morphometrics
soft rays: 9. Can be diagnosed from other congeners in Europe by the combination of the following characters: one lamina circularis; caudal peduncle 1.9-2.3 times longer than deep; upper caudal-fin base with a single, indistinct black spot or without black spot; back with 1-3 postdorsal blotches, almost roundish with convex lateral margins; zone Z1 indistinct with few very small to small spots, narrower than zone Z2; on predorsal body, zone Z3 formed by few very small spots in males, narrower or as wide as Z2; on postdorsal body, zones 1-3 confluent in males; distance between tip of pectoral fin and origin of pelvic 73-82% of pelvic-fin length (Ref. 75104).
Found in still waters of lakes on mud bottom (Ref. 59043). Congeners are oviparous, possibly with distinct pairing during breeding (Ref. 205).
Life cycle and mating behavior
Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae
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).
