Comments: In the type locality region, this species occurs usually in marginal emergent plants (mainly wild rice, Oryza spp.), rafts of floating macrophytes (including grasses, e.g., <i>Paspalum</i>, and water hyacinths, <i>Eichhornia</i> spp.), and decaying plant matter along the edges of low-conductivity blackwater floodplain ria lakes (e.g., lago Tefé, lago Amanã, and lago Caiambé), and along river and oxbow lake margins.  Feeds on aquatic insect larvae (primarily Chironomidae), and other
  small aquatic invertebrates in the type locality.  Spawns in floating macrophytes during the rising and high water period (Ref. 116763).
