Environment: milieu / climate zone / depth range / distribution range
Freshwater; demersal; pH range: 6.0 - 8.0; dH range: 2 - 25; depth range - m (Ref. ), usually - m (Ref. ). Tropical; 22°C - 26°C (Ref. 13371)

Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 5.3 cm SL male/unsexed; (Ref. 35381)
Occurs in the upper reaches of basins, may be abundantly caught in creeks with flowing waters, sandy to sandy-muddy bottoms, width 3 to 5 m and depth 0.3 to 2 m. Feeds by driving their snout into the substrate up to the eyes and drawing out dead snails, decaying leaves, worms or other benthic organisms. They can also catch their prey in open water (Ref. 35381).

Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref. 93245
Trophic level (Ref. 69278
): 2.6 ±0.21 se; based on food items.
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low vulnerability (10 of 100) .
