Taille / Poids / Âge

Maturity: L_m ? range ? - ? cm
Max length : 5.3 cm TL mâle / non sexé; (Ref. 38376)

Usually found in ponds, ditches, slow flowing streams, both clear and turbid, in both open and shaded areas. A voracious species which feeds on small crustaceans, insects and mollusks (Ref. 12225). Gregarious and non-aggressive, it is reputedly easy to rear and to reproduce in the aquarium (Ref. 27188). Maximum length questionable (Ref. 38376).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01413 (0.00671 - 0.02974), b=3.08 (2.91 - 3.25), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Niveau trophique (Ref. 69278): 3.4 ±0.44 se; based on food items.

Résilience (Ref. 120179): Haut, temps minimum de doublement de population inférieur à 15 mois (tm<1).

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

Catégorie de prix (Ref. 80766): Unknown.
