Widespread in mildly brackish water in canals and drainage ditches at the edges of swamps, but rarely found in freshwater. Feeds on mosquito larvae and has at times been used for control in ponds and reservoirs (Ref. 35237).

Levenscyclus en paargedrag Maturities | Voortplanting | Spawnings | Egg(s) | Fecundities | Larven

Males are very active and also approach the females of other Poecilinae. [Females produce 6 - 10 offspring which follow their mother for a few hours after birth, referring to Ref. 35237.] After 28 days gestation, female gives birth to 100 young or more. Sexual maturity is reached after 3-4 months (Ref. 2060).

Estimates based on models

Fylogenetische diversiteitsindex (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01047 (0.00655 - 0.01674), b=3.27 (3.14 - 3.40), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).

Trofisch niveau (Ref. 69278): 2.3 ±0.1 se; based on diet studies.

Weerstandsvermogen (Ref. 120179): Gemiddeld, minimale populatieverdubbelingstijd 1,4-4,4 jaar (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
