Maturity: Lm ? range ? - ? cm
Max length : 7.0 cm TL male/unsexed; (Ref. 27139); max. reported age: 1.00 years (Ref. 12193)
Seasonal toothcarp living in waters that dry up during the dry season. The adult fishes die but the eggs survive in the mud and hatch in the next rainy season. Feeds on worms, crustaceans and insects (Ref. 7020). Bottom spawner, 4 months incubation. Is easy to maintain in the aquarium (Ref. 27139).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5039 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01995 (0.00906 - 0.04395), b=3.01 (2.83 - 3.19), in cm total length, based on all LWR estimates for this body shape (Ref.

Trophic level (Ref.
69278): 3.3 ±0.40 se; based on food items.
Resilience (Ref.
120179): High, minimum population doubling time less than 15 months (tmax=1).
Fishing Vulnerability (Ref.
