Tetra Amanda (Hyphessobrycon amandae) – content, breeding

Tetra Amanda (Hyphessobrycon amandae) GÉRY UJ, 1987.

Hifessobrikon: from ancient Greek (hyphesson), which means “smaller growth”, and is used as a prefix in this case, as well as the common name Brikons.

Tetra Amanda is a tiny graceful fish that can decorate any aquarium. It was discovered not so long ago in 1987: Heiko Bleher first described it, calling it after his mother, and professionals and amateurs call Amanda’s tetra a fiery dwarf tetra and a red nano-tetra.

In nature, it inhabits swamps and lakes, slow-flowing streams, and small tributaries of the Amazon in central and western Brazil, flowing through the rainforest of the Brazilian state of Mato Grosso.

Brazil: Mato Grosso State, Rio Das Mortes River.

A large number of trees provide a permanent shade above the water, where a lot of fallen leaves and branches gather, saturating the water with tannins, which gives it a yellowish-brown color and creates a mildly acidic environment.

The climate of Mato Grosso is typical for the Amazon rain forest, very humid and warm (Rio Das Mortes )

The Rio das Mort is a tributary of the Araguaia, the main tributary of the Rio Tokantins in the lower part of the Amazon basin in central and western Brazil, although the full range of populations of N. amandae in the Araguaia system remains unclear.

In fish, the body is elongated and slightly flattened at the sides. They are painted in a rich reddish-orange color, but its intensity depends largely on the conditions of detention. The rim of the eyes is golden hue, unpaired fins are reddish.

At the top of the dorsal fin and on the forked tail are light gray or cream specks.

Amanda’s female theater

There are no color differences, but females are distinguished by a rounded belly in the prespawning period and by a large size of the swim bladder, which in males has a pointed irregular shape. In addition, males are smaller and brighter colored.

Amanda’s theater male

The size of the theaters of Amanda usually does not exceed 15 – 20 mm, but sometimes there are individuals up to 30 mm.

Arrangement and parameters of the aquarium:

The dwarf tetra is a schooling fish and feels confident in the company of at least 8-10 relatives, if more – then even better. The volume of the aquarium is chosen at the rate of about 10 liters per pair, but at least from 45 * 30 cm.

Tetra Amanda (Hyphessobrycon amandae) undemanding to the design of the aquarium, but against the background of dark soil looks much more impressive. It is advisable to place floating plants in the pond, giving the usual shade to the fish, and plant the rest tightly to create additional secluded places, while leaving free space for swimming.

The substrate needs a soft, sandy, and with the help of kryagi and branches, the natural habitat is recreated.

Water parameters: 22-28 ° С, optimal 24-26 ° С, pH 5.0 – 7.0, kH 7-14, gH 8-20.

Filtration with aeration should be moderate, the lighting scattered and dimmed. A quarter of water is changed weekly.

Tetra Amanda (Hyphessobrycon amandae) possesses a peace-loving character, so it can be maintained with the same calm species: pygmy corridors, otozinclus, nanostomuses, rassets, danios, small iris and shrimps; are ideal neighbors for Apistograms and other dwarf cichlids.

Neighborhood with large or aggressive fish is contraindicated.

Nutrition: in nature, it feeds on small invertebrates and other zooplankton.

Unpretentious and take all kinds of food: live and frozen Artemia, Cyclops, Daphnia, Moin, mixtures of flakes, pellets.

When drafting a diet, it is important to make it as diverse as possible, since this directly affects the brightness of the color and do not forget that this Dwarf Tetra has a very small mouth and, if necessary, chop food.

Reproduction: Breeding Amanda’s tetra is a simple process even for inexperienced aquarists, although it has a number of features.

Before spawning, females and males are kept for some time separately and diversely and abundantly fed.

Fish are able to breed in the general aquarium, but then there is little chance that the fry will survive. It is better to place the producers in a separate shaded container with a volume of about 20 liters with Javanese moss or another substrate suitable for spawning.

At the bottom of the spawning tank, it is better to place some kind of mesh so that the eggs pass through the cells, but in such a way that the producers cannot reach them.

Herbal mats, widely available in plastic, can also be used and work well.

Water parameters in the spawning aquarium: 27-29 ° C, GH 0.2-0.5, pH 5.5-6.0.

Easy filtering will provide a small airlift / air filter, you can use only a spray.

Spawning can be a group with a predominance of males or a pair, but in any case, this process is not only interesting, but also beautiful. To obtain the largest number of fry, it is necessary to select the brightest males and females with a well-pronounced rounded belly and plant them in a spawning aquarium in the evening.

Already the next morning about 120-150 eggs will appear in it, and at this moment adult fish should be deposited immediately, destroying their offspring.

The incubation lasts 24-36 hours, and after a few more days the fry are able to independently swim and take micro-food — an infusorian shoe, rotifer or a special dry food, then Nauplii cyclop and Artemia ..

Coloring begins to occur in young at about one month of age, and at four months the fish are already reaching maturity.

When creating favorable conditions Tetra Amanda (Hyphessobrycon amandae) lives in the aquarium for about 3 years.
