Biology     Glossary (e.g. epibenthic)

Occurs in crystalline water streams with flow from 0.05 to 0.70 m3/s. Prefers to occupy the water surface and the spaces among plants roots and tree branches. Usually aggregates with up to 2 dozens individuals, but schools with about 150 individuals have also been observed. An omnivorous fish which feeds on insects, plants, crustaceans, filamentous algae and fish (Ref. 82392).

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=0.01549 (0.00660 - 0.03634), b=3.06 (2.88 - 3.24), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.0   ±0.3 se; based on size and trophs of closest relatives
Resilience (Ref. 120179):  High, minimum population doubling time less than 15 months (Lm=2.5-2.6).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
