Collected from the shallowest parts of a small stream, about 10-20 cm deep, where the larger specimens are found in places with more dense aquatic vegetation and juveniles in places more exposed to sunlight. It is a typical stream of central Brazil, locally known as Vereda or Buritizal (i.e. streams dominated by the buriti-palm Mauritia flexuosa L.), with orange clay bottom, in open vegetation of the Brazilian Cerrado and water was clear, with pH 5.3 (Ref. 59346).

Estimates based on models
Fylogenetische diversiteitsindex (Ref.

50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00977 (0.00315 - 0.03034), b=3.03 (2.78 - 3.28), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trofisch niveau (Ref.

Weerstandsvermogen (Ref.
