Silvertip tetra, a small freshwater fish (Hasemania nana) found in Brazil
Given the origins of the silvertip tetra, namely blackwater rivers whose chemistry is characterised by an acidic pH, low mineral content and the presence of humic acids, the species is adaptable to a wide range of conditions in captivity, though deviation from the soft, acidic water chemistry of their native range will impact severely upon breeding and fecundity.
