Ideally, the hardness of the water should be below 16 degrees Celsius, and the temperature should be kept at 23 and 27 ° C. As they belong to the group of shoals, it is advisable that you introduce at least eight specimens so that they feel safe and protected. Try the way they are of similar characteristics because their size could become the talk of other fish.

Among the best known, we find the following:
Black or monitor tetra fish: it is characterized by being elegant and with a striking colour, ideal for decorating community aquariums. It has two black stripes on its elongated body, it has a long anal fin for efficient swimming, and its two fins are black.
Bleeding fin tetra fish: as its name implies, this genus has fins coated in bright red colour, so it seems that it is bleeding all the time. Their body is compressed, and in some cases, they can grow up to 7 centimetres in length, so they require a wide area for nothing to their liking.
Red tetra fish: it belongs to the group of characids, so it is recommended for beginners. In this case, the head is usually larger than the body, so its swimming is not as efficient, and its lower jaw is more developed than the upper jaw.

Reproduction of the x-ray tetra
In this type of species, reproduction is a bit difficult, so before courtship, it is recommended to prepare a fairly large aquarium to avoid parents having any confrontation with other genera. Then the first thing you should do is cover almost the entire surface of the aquarium with floating plants, either artificial or natural; in addition, the soil needs to be densely planted preferably with a cover plant.
You must make sure that the aquarium incorporates plants such as Cabomba Carolina to make the laying much safer. When everything is ready, it is necessary to optimize the temperature by one or two degrees, then two females and three males must be introduced so that the courtship begins, surely the female will lay on the ground cover plants.
In some cases, the female can spawn between 100 to 200 eggs, so once the act is done, removing the parents from the aquarium prevents them from devouring the laying. Now we only have to wait 48 hours for the eggs to hatch, the tetra rat x fish at birth feed on their own sac for life since they cannot perfectly digest their food.
Tips for breeding
During the first three days, the baby will not be able to feed on live food, so it is recommended to give them small portions of egg yolk, as up to five days they begin to swim, it is necessary to throw the food at a short distance. After this time you should feed them as you usually do with other fish so that their immune system and defences develop correctly.
