Max length : 2.4 cm SL Männchen/unbestimmt; (Ref. 59346); 2.3 cm SL (female)

Collected from the shallowest parts of small streams, about 10-20 cm deep, locally known as Veredas or Buritizais (the streams are dominated by the buriti-palm Mauritia flexuosa), with orange clay bottom, in open vegetation of the Brazilian Cerrado. During the collection of the type series, the water was clear, pH 5.8 (Ref. 59346).

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=0.00977 (0.00315 - 0.03034), b=3.03 (2.77 - 3.29), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.1 ±0.4 se; based on size and trophs of closest relatives

Widerstandsfähigkeit (Ref. 120179): hoch, Verdopplung der Population dauert weniger als 15 Monate. (Preliminary K or Fecundity.).

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