Short description
Identification keys | Morphology | Morphometrics
Dorsal soft rays (total): 10; Anal 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).
Body shape (shape guide): elongated.
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).

50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00513 (0.00234 - 0.01125), b=3.09 (2.92 - 3.26), in cm total length, based on LWR estimates for this Genus-body shape (Ref.
