Maturity: L_m ? range ? - ? cm
Max length : 6.5 cm SL maschio/sesso non determinato; (Ref. 7020)

Inhabits small rivers with little current and in swamps where they are very common. Forms groups where the males dominate to defend their territory. Is highly appreciated by aquarists (Ref. 12225). Feeds on worms, crustaceans and insects (Ref. 7020). Aquarium keeping: in groups of 5 or more individuals; minimum aquarium size 60 cm (Ref. 51539).

Life cycle and mating behavior Maturità | Riproduzione | Deposizione | Uova | Fecundity | Larve

At spawning time in captivity, male and female swim alongside one another. Several batches of 1 to 5 eggs are laid among the fine-leaved plants, with a total of up to 200 eggs in some cases; eggs hatch in 30 to 40 hours and fry are free-swimming about six days after (Ref. 7020). Between 24°-27°C, eggs hatch in 24 hours (Ref. 205).

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=0.00646 (0.00321 - 0.01300), b=3.04 (2.86 - 3.22), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Trophic level (Ref. 69278): 3.3 ±0.39 se; based on food items.

Resilienza (Ref. 120179): Medio, tempo minimo di raddoppiamento della popolazione 1.4 - 4.4 anni (Fec = 200).

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