Reproduction of the tetra x-ray
In this type of species it is a bit difficult to reproduce, so before courtship it is recommended to prepare a fairly large aquarium to prevent parents from 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, whether artificial or natural, in addition the soil needs to be densely planted preferably with an upholstery plant.
You need to make sure that the aquarium incorporates plants like Cabomba Carolina to make the laying much safer. When you have everything ready it is necessary to optimize the temperature one or two degrees, then you must introduce two females and three males so that the courtship begins surely the female will do the laying on the upholstery plants.
In some cases the female can get to shed between 100 to 200 eggs, so once the act is done it is necessary to remove the parents from the aquarium to prevent them from devouring the laying. Now it only remains to wait 48 hours for the eggs to hatch,the tetra-time x-born fish feed on their own life sac since they can not perfectly digest their food.
Tips for breeding
During the first three days the calf 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 must feed them as you usually do with other fish so that their immune system and defenses develop correctly.

It is recommended that the middle zone is free since most of the time is spent there, in addition to the background of being prepared by dark gravel to attenuate the clarity. For optimal maintenance it is best to opt for an aquarium where at least 60 liters fit. The water must have a pH between 6.0 to 7.5 so that the species has a better oxygenation.
Being a small species it is important that the hardness of the water is kept below 16° C since they are not able to withstand sudden changes. To avoid creating pests or bacteria that can harm the fish it is important to change the water at least once a week, surely your species will appreciate it.
