Etymology:

Hasemania: Because of John D. Haseman, the American collector of fishes.

General Notes:

Silver tip tetras are often listed as good community fish but anyone who has kept them will know that *they are in fact fin nippers. A shoal of these fish would look great in a planted tank or they could possibly be kept in a community set up if their tank mates were chosen very carefully - no slow moving fish or fish with long flowing fins. In the aquarium silver tip tetras should be kept in a shoal of at least six individuals. Silver tip tetras will be seen at their best in a well planted tank with subdued lighting and dark substrate.

Feeding

Silver tip tetras are quite bold feeders and relatively unfussy. They will accept flake food, small pettleted food, freeze dried food but this should be supplemented with suitably sized live or frozen food.

Sexing

Male silver tip tetras have a coppery colour while females are grey.

Breeding

Silver tip tetras like most other tetras are egg scatterers. The male chases the female and during the chase the eggs are laid and fertilised over fine leaved plants. A separate breeding aquarium is essential because the adults will prey on both eggs and fry alike.

Wild status

The wild population of silver tip tetras has not been evaluated and so its status is unknown.
