Size / Gewicht / Alter

Maturity: L_m ? range ? - ? cm
Max length : 4.9 cm TL Männchen/unbestimmt; (Ref. 116983)

Occurs along the coastal zone and prefers water bodies with little current. Lives in groups. Feeds on worms, small insects, crustaceans and plants (Ref. 7020). The males are generally very much smaller and more svelte than the females. It is a very prolific species and its reproduction can easily be carried out in the aquarium (Ref. 12225). With an incubation temperature of 26°C, hatching of the eggs occurs within 48 to 60 hours (Ref. 27188). Maximum length questionable (Ref. 38376). Aquarium keeping: in groups of 5 or more individuals; minimum aquarium size 60 cm (Ref. 51539).

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=0.01148 (0.00656 - 0.02009), b=3.09 (2.95 - 3.23), in cm Total Length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Trophic level (Ref. 69278): 3.2 ±0.41 se; based on food items.

Widerstandsfähigkeit (Ref. 120179): hoch, Verdopplung der Population dauert weniger als 15 Monate. (Preliminary K or Fecundity.).

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