Grootte / Gewicht / Leeftijd

Maturity: L_m ? range ? - ? cm
Max length : 13.1 cm SL mannelijk / geslacht onbekend; (Ref. 38289)

Long-lived and gregarious species. Occurs over sandy substrate (Ref. 27188). Frequently found in the rapids, thereby suggesting the need for a lot of space and well-aerated water for maintenance in the aquarium. Oviparous (Ref. 205). Can be caught using lines with crushed meat as bait but is also known to feed on plants. Is capable of powerful leaps out of the water (Ref. 12225).

Estimates based on models

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

Bayesian length-weight: a=0.01072 (0.00498 - 0.02308), b=3.09 (2.91 - 3.27), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).

Trofisch niveau (Ref. 69278): 2.6 ±0.27 se; based on food items.

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

Prijsklasse (Ref. 80766): Unknown.
