1. Prepare a breeding tank: Before breeding ten fish, you should prepare a breeding tank as a breeding container. Clean water should be poured into the breeding tank, and the water temperature should be controlled between 26-29 degrees Celsius, which is the most suitable water temperature for their breeding.
2. Parent fish in the tank: After the breeding tank is prepared, the parent fish in the breeding period can be put into the breeding tank. At the beginning, they can be separated by baffles, and after 1-2 days, they are familiar with some, remove the baffles, and then they can breed. However, it should be noted that it is possible that the male and female fish can not see each other and fight. At this time, it is necessary to change the parent fish and then reproduce.
3. Fishing out the parent fish: After the parent fish is put into the tank, pay attention to keeping quiet and do not frighten them, so as not to stop their reproduction. After they see the right eye, they will begin to reproduce and lay eggs. When they have finished spawning, the parent fish should be taken away, leaving only the eggs. Because this kind of fish may eat their own eggs, it is better to fish out the parent fish so as not to eat the eggs by mistake.
4. Hatching small fish: Keep the water temperature well, and the eggs can be hatched after a few days of cultivation. Newly hatched fish are fragile and easy to die, and need to be fed with egg yolk water to provide them with nutrients to help them grow.
Generally speaking, ten fish can be sexually mature after 7-8 months of growth, and can reproduce. However, it is more recommended to breed male fish with a body length of about 20 cm and female fish with a body length of about 16 cm.
