Abstract
A new dwarf genus and species, Tucanoichthys tucano, less than 17 mm in maximal standard length, is described. It comes from a brook tributary of the Rio Uaupés, upper Rio Negro basin, in Brazil. Its affinities are discussed. It belongs to the Characidae in the broad sense, but could not as yet be attached to a particular subfamily. Its ecology and behaviour are also described, following observations in the field as well as in the aquarium
