Silvertip Tetra (Hasemania nana) Fish Species Profile

Article Contains

Silvertip Tetras are hardy, good looking and an active shoaling fish that does well in a community aquarium. However, they are slightly more aggressive than other comparable smaller tetras occasionally nipping fins of other similarly sized tetras. They can adapt to a wide range of water parameters, making them ideal for the beginner aquarists.

The body of Silvertip Tetra is transparent except for the fact that their bodies have an overall gold to a copper sheen. During the night, the copper and black colours become silver as the fish rests. The colour then returns once the fish becomes active in the morning.

You can see a little bit of silver pattern beside the eyes. Silvertip Tetras display a black stripe that goes from the middle of the body to the end of the tail fins. The dorsal fin has a golden-yellowish colour with a little bit of silvery-white on the tip. The anal fin has quite a similar colour to the dorsal fin. They differ from most other Tetras as they lack a small adipose fin.

Origins of the Silvertip Tetra

Silvertip Tetras are native to Sao Francisco river basin in Brazil in South America. They inhabit slow-moving water in creeks, small tributaries and streams away from the main river channels. You can find them in both black and white water environments with an abundance of vegetation for shelter, breeding and food.

Diet

The Silvertip Tetra is relatively easy to feed. These fish will readily accept anything offered. For the best colours and condition, offer them regular meals of small frozen and live foods such as daphnia, bloodworm and brine shrimp as well as high quality dried flakes and granules.

Sexing the Silvertip Tetra

It is relatively challenging to differentiate males from females. The males tend to be more intensely coloured and slimmer than females, whereas the females are more pale and silvery with a sightly larger stomach.

Breeding the Silvertip Tetra

The Silvertip Tetra is quite easily bred, although you will need to set up a separate breeding tank if you would like to increase the yield of fry.

The tank should be dimly lit and contain clusters of fine-leaved plants such as java moss. Spawning mops are also suitable. This will give the fish somewhere to deposit their sticky eggs. You could also cover the bottom of the tank with some mesh. This mesh should be a large enough grade so that the eggs can fall through it, but small enough so that the parents cannot reach them.

These Tetras can be spawned in a group, with half a dozen individuals of each sex being ideal. Condition them with plenty of live and frozen foods and spawning should not bestow too many problems.

Alternatively, you can spawn them in pairs. Under this method, the fish are conditioned in female and male groups in separate tanks with a high-quality diet of frozen and live foods, with a slightly higher temperature than you usually have in the main tank and somewhat acidic water.

When the females are full of eggs, and the males are presenting their best colours, select the best-coloured male and the healthiest female and place them in the breeding tank. The couple should spawn the next morning.

In either situation, the adults will consume the eggs if given a chance and should be removed at the first chance.

The eggs will hatch in around 24-36 hours, and the fry will become free swimming 3-4 days after that.

It would be best to feed the fry with infusoria type foods for the first few days until they are big enough to accept brine shrimp nauplii and microworm. The eggs and fry are sensitive to light in the early stages, so it would be a good idea to keep the lights dim or maybe even off.
