Specimens were collected from a creek and in wide open environments, as river channels and bays of the upper Rio Paraguay basin in the periodically flooded areas known as the Pantanal. Known to be a zooplanktivore which also eats insects. Stomach contents predominantly has microcrustaceans (cladocerans, copepods and ostracods); insects (ephemeropterans, coleopterans and hemipterans); and/or small amounts of water mites, rotifers, fish scales, bryozoans, unidentified eggs, detritus, and sand (Ref. 57707).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5625 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00955 (0.00403 - 0.02261), b=3.08 (2.87 - 3.29), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

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

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