Length at first maturity / Size / Gewicht / Alter

Maturity: L_m ?, range 14 - ? cm
Max length : 11.0 cm SL Männchen/unbestimmt; (Ref. 36695)

Facultative air-breathing in the genus; Occurs in ponds (Ref. 11229) and forest creeks rich in plant debris (Ref. 35381). Benthic fish which feeds on a wide range of food, including organic debris from the bottom. Spawns eggs on sandy substrate, in groups. Unlike the other species of Aspredinidae, the female does not carry her eggs (4,000 to 5,000 per spawning) in bags (cotylophores). It swims with undulating motion of its body and tail, rhythmically ejecting water from its opercles, thus resulting in a forward propulsion (Ref. 35381). Aquarium keeping: needs fine gravel or sand; minimum aquarium size 80 cm (Ref. 51539).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5001 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00324 (0.00134 - 0.00780), b=3.03 (2.83 - 3.23), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.8 ±0.60 se; based on food items.

Generation time: 1.4 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.

Widerstandsfähigkeit (Ref. 120179): mittel, Verdopplung der Population dauert 1,4 - 4,4 Jahre. (Fec = 4,000).

Fishing Vulnerability (Ref. 59153): Low vulnerability (18 of 100).
