All specimens captured in rapids upstream. Captured with hooked-lines baited with Podostemaceae, arrows, and rotenone. Podostemaceae seems to be their main diet. Very similar to Tometes trilobatus. Both species are important for Amerindian tribes Wayãpi and Wayana. Could be endangered by human threats like subsistence fisheries, habitat destruction by mining activities, and dams (Ref. 47182).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5078 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.02291 (0.01040 - 0.05047), b=3.00 (2.82 - 3.18), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Resilience (Ref. 120179): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Moderate vulnerability (45 of 100).

Price category (Ref. 80766): Unknown.
