A riverine species collected some distance up a low-gradient swampy tributary of the Rio Negro (the Rio Jufari), Brazil and in the main river, in both cases the water generally darkly tinted, acid (pH 4-5) and low in dissolved ions. Feeds on dipteran larvae and pupae; also cladocerans. Males mature at 1.43-1.62 cm SL; females at 1.59-1.82 cm. Ovarian eggs are creamy or pale orange.
