Comments: The type locality is a second order stream, known as an igarapé, and surrounded by secondary forest in regeneration. The bottom of is mainly composed of silt, with litter on the margins and few branches and trunks of a diameter greater than 10 cm. In the pools, there is flocculant sediment that is easily disturbed from submerged litter and macrophytes were found at sites with a little more water flow. Most individuals were only observed in more lentic environments, swimming in small schools of 5 to 20 individuals. Individuals also observed to swim alone and together with other species of Characidae, such as <i>Moenkhausia phaeonota</i> and <i>Hyphessobrycon heliacus</i> near igarapé margins with depth ranging from 20-40 cm. Individuals were also sometimes observed foraging among the submerged litter in the igarapé margins. This species also inhabits faster water, no vegetation and substrata consisting of sand and mud (Ref. 118106).
