The silvertip tetra (Hasemania nana) is a species of characid freshwater fish omnivores native to streams and creeks in the São Francisco basin in Brazil, but frequently kept in aquariums.

[2] The tetras are transparent with their gold colors and have a black stripe that runs along the mid to back section of their bodies.

When they are preparing to breed, the male will be brightly colored while the female will be swollen.

When they breed, the female scatters their eggs among vegetation while the male fertilizes them.

[3] The genome was fully sequenced in 2013, by standard PCR, and found to be 16,581 base pairs long.
