| Varieties: | No cultivated colour strains of consequence — the wild-type fish is what is sold, and the copper colour of a mature male is selection enough. Some suppliers offer stock selected for deeper colour, and quality varies between farms, but there are no established named varieties. Almost all trade fish are commercially bred. The genus is small and this is the only member commonly available. Hasemania is distinguished from other characins by the absence of an adipose fin, and the species has been shuffled between genera over the years — older references list it as Hemigrammus nanus or Hyphessobrycon nanus, and both names still appear on shop labels. Comparable community tetras include the black phantom, red phantom, rosy and serpae tetras, all of which are similar in size and rather more brightly coloured; the serpae shares the nipping tendency and is worse for it. For a hardy copper-toned tetra in hard water, this species is the more adaptable choice. |

Silvertip Tetra (Hasemania nana) is a species of fish in the family Acestrorhamphidae. It is native to South America (São Francisco basin, Brazil). The silvertip tetra is a copper-coloured fish with white-tipped fins, and it is easier to keep than most small tetras — with one behavioural condition attached. It reaches 50 mm standard length. Mature males run a warm coppery gold that deepens with condition; females are paler and more silver, and both carry the bright white fin tips that name the fish. There is a useful anatomical oddity: the genus Hasemania is one of the few characin groups that lacks an adipose fin, the small fleshy fin between the dorsal and the tail that almost every tetra has. If you cannot find it, that is the reason. The condition is numbers. Kept singly or in small groups it can be nippy, and it needs six as an absolute minimum with ten or more preferred.
