Tetra Amanda (hyphessobrycon amandae) is a small bright freshwater fish that can decorate any aquarium. She was found in 1986 in the basin of the river Araguaya in Brazil.
The representative of the Kharacin family received her name in honor of the mother of her discoverer Heiko Bleher – Amanda Bleher. Other fish names are red nano-tetra and dwarf tetra.
Tetra Amanda – freshwater fish of the family of the charatsin of the order Characiformes
Tetra Amanda – the smallest tetra, reaches only 1.5-2.5 cm, with the males a little smaller than females. The body is oval, slightly flattened on each side, it has an orange-red color. The brightness of shades depends on the environment.
In nature, there are pure orange and yellow individuals living in separate colonies.
Getting into the new aquarium, tetra can become pale orange or pinkish, so as will be experiencing stress. However, over time, when the fish gets used to the new conditions, its color will become bright again. Amanda has a forked tail, which, like the dorsal fin, is adorned with bright spots.
With good conditions, tetra can live up to 2−3 years.
In nature, the dwarf tetra lives in lakes, marshes and slow-flowing streams in the tropical forests of the Brazilian state of Mato Grosso. They prefer soft acidic water, live near aquatic plants and sunken tree trunks.

Tetras in nature live in flocks of 10−15 relatives and more, therefore, in one aquarium it is advised to contain at least 7−8 such fish. The minimum height of the aquarium – 0.3 m, length – 0.45 m. For one pair should be 10 liters of water.
The content of Amanda’s tetra suggests the presence of a large number of plants in the aquarium. Tetras, accustomed in nature to shaded places, in the aquarium also need to create such conditions.
To do this, you can use algae with long stems, stones, snags or special decorations. But do not forget that Amanda is very mobile, so there should be a place in the aquarium for their free movement.

The soil should be selected fine and soft. It is better if it is dark, because on its background Amanda will look as impressive as possible.
Dry leaves (for example, alder or oak) can be placed on the bottom. They will give the water a shade familiar to these fish. In addition, the leaves will saturate the water with beneficial substances, beneficial bacteria will develop on the flooring.
The main thing – do not forget to regularly change the foliage.
Aquarium lighting should be soft and diffused. The water temperature is 23−28 C. In nature, tetras live in soft water with an acidity of about 6.6, but in an aquarium they are able to adapt to an acidity of 5–7 and a hardness of 5–17 ° dGH.
The main thing is to ensure the stability of the water characteristics, as the fish do not tolerate drastic changes.

Amanda does not live in turbulent rivers, so a filter with a weak stream should also be installed in an aquarium. To ensure cleanliness, a quarter of the volume of water should be changed once a week.
Once a month it is worth cleaning the scenery and the ground.
Zooplankton and small invertebrates are habitual food of Amanda in their natural environment. Living in an aquarium, tetras are unpretentious in food.
Both live and frozen fodder are equally suitable for them – small bloodworm, Cyclops, Artemia, Moin, Daphnia. Also dry flakes and granules will do.
But it should be remembered about the small size of the fish, so you need to pick up the appropriate small food or grind large.
It is better to feed tetras several times a day in small portions. The diet is desirable to make a variety – it will positively affect the appearance and activity of the fish.
Dwarf Amanda peaceful, get along well with the same small non-aggressive species. Other types of tetras will be good companions for them. Also in the general aquarium with them you can safely place the fish of the following types:
- swordtails;
- guppy;
- rasbory;
- danios;
- iris;
- neons;
- corridors.
It is important that in the aquarium with Amanda there were no large aggressive fish.
In addition, since Amanda do not eat feed from the bottom, there will be useful to make them small friendly catfish, which will eat up leftover food from the ground. Thanks to this combination of species, the water in the aquarium will stay clean longer.
It is worth taking care that in the aquarium with Amanda there were no large aggressive fish. They can eat tetras.
But even if this does not happen, the bright fish will be under constant stress from such a neighborhood, which will negatively affect their appearance.

Breeding tetra Amanda does not cause much difficulty. Sexual maturity is achieved by these fish by the age of four months. Distinguish females can be on the rounded abdomen.
In addition, females are slightly lighter and larger than males.
If Amanda is the only inhabitants of the aquarium, reproduction can occur without human intervention. Females lay eggs on small-leaved algae, and fry can feed on protozoa, which form on dry leaves placed on the bottom.

But there is a chance that adults will eat offspring, therefore, for reliability, it is worthwhile to acquire an additional aquarium for fry and follow the recommendations:
- Choose the brightest and most active fish.
- Before spawning, place the females and males separately.
- Increase and diversify the diet.
- Prepare a separate aquarium with a volume of about 20 liters, place Javanese moss on its bottom, and on top of it a grid with micro cells or a plastic “grass mat”. Water should have a temperature of 27−29 ° C, acidity 5−6.5. The light should be muted, diffused, filter – light.
- During the spawning period (in the evening) place the females and males together in this separate aquarium.
- When eggs appear (usually this happens the next morning), adult fish should be returned to the main aquarium.
