Levenscyclus en paargedrag
Maturiteit | Voortplanting | Paaien | Eieren | Fecunditeit | Larven
Male pursues a slow-moving female and upon catching up with the female, will begin shuddering from side to side while the pair is oriented parallel to each other; the pair positions themselves close to submerged vegetation; male assumes a slight head-down position , with his anal fin curled under the female's vent; the pair begins trembling until a single large egg is released; each female produces about a dozen eggs per day; eggs hatch in about a week; no parental care (Ref. 44091).

Estimates based on models
Fylogenetische diversiteitsindex (Ref.

50 = 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00112 (0.00070 - 0.00179), b=3.16 (3.03 - 3.29), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref.
93245).
Trofisch niveau (Ref.
