Biologie     Verklarende woordenlijst (bv. epibenthic)

Adults occur in warm springs, canals and ditches with typically slow-moving water, silt bottoms and weedy banks (Refs. 5723; 44091, 44894). Also inhabit creeks and swamps (Ref. 44894). Feed on worms, crustaceans, insects and plant matter (Refs. 7020; 44091). Used for genetic research (Ref. 4537). Several color varieties are popular aquarium fishes, where they attain sexual maturity after 3-4 months and reproduce easily (Ref. 1672). Aquarium keeping: minimum aquarium size 60 cm (Ref. 51539).

Estimates based on models

Fylogenetische diversiteitsindex (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01023 (0.00456 - 0.02295), b=3.13 (2.95 - 3.31), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trofisch niveau (Ref. 69278):  3.2   ±0.40 se; based on food items.
Weerstandsvermogen (Ref. 120179):  Hoog, minimale populatieverdubbelingstijd minder dan 15 maanden (tm<1).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
