Ember tetra (Hyphessobrycon amandae ) – one of the most popular and smallest tetras in freshwater aquariums. This little fish is also known as the dwarf snapper.


The amanda burst comes from South America . The species inhabits the state of Mato Grosso in Brazil, found primarily in smaller rivers, streams, tributaries, and oxbow lakes. It is often harvested under floating plants.

Characteristics and disposition

Probably the smallest of the tetras found in aquariums. They are only about 2 cm long. Amanda’s bubbles come in two color forms: yellow and orange-red. In nature, they occur separately and do not interbreed, therefore it may turn out that they are two separate species. The bright red color is fully revealed only in water of excellent quality.

Gender quite difficult to distinguish . Males are usually slightly smaller, slender and more colored than stocky females (it is especially visible during the spawning period), but it is not a rule. They swim in the middle zone of the aquarium and swim nicely in the shoal. The minimum is 6 specimens, preferably 10 or more. They feel and present themselves much better in a larger group of their representatives.

Nutrition and feeding

They eat small dry, frozen and live foods.


A 30-liter aquarium is sufficient for a group of 8-12 fish. Their coloration can be admired in all its glory in a tank with not too bright lighting and a dark substrate, densely planted on the sides, with space for swimming. To reproduce their natural environment, we will need a sandy substrate, marsh roots, dry leaves and water filtered through a peat filter. The species is very gentle and may not be able to compete with larger, vigorous fish.

Their small size makes it impossible to keep them in the company of gouramis or scalars , for which they can become food. In an appropriately larger tank, good company will be e.g. otosek , cuirass , ramireza cichlid , microorganisms (e.g. fringe , Beckford) and other small, peaceful species of fish as well as dwarf shrimps, e.g. babaulti or the popular red cherry.


It can be bred in groups or in pairs. For the reproduction of fish in larger quantities, we need a 40-liter aquarium (10-15 l is enough for a couple). Place small-leaved plants in the tank, e.g. mosses, on which the fish can spawn. Plants should cover about 50% of the aquarium area.

Instead, we can use artificial aquarium mops. We shade the aquarium. Amanda bubbles wipe in acidic and soft water in the range of 5.5-6.5 pH, 1-5 ° dGH, at a temperature of 26-28 ° C. Obtaining such water parameters is possible by filtering it through peat or using an RO filter. When breeding rapids in a group, there should be one male for each female.

Before the planned spawning, the fish are fed more often with live or frozen food. When reproducing the rapids in pairs, before the planned spawning, females should be separated from males and fed as above. After a few days, when the females will become round around the abdomen, select a few spawners and place them in the previously prepared tank in the evening. Spawning usually takes place the next morning. The adults eat the roe, so we catch both parents right after spawning.

Hatching takes 24-36 hours. After another 3-4 days, the fry begin to swim on their own. During the first days, we feed the young with micro foods, e.g. plankton, until they are large enough to accept brine shrimp larvae or micro nematodes.
