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).
