How do pearl vest fish reproduce? How old can they reproduce

Pearl vest fish can reproduce when they are generally 10 months old. Usually choose 2-year-old fish with a body length of about 7 or 8 cm, and the reproductive success rate is higher. It's not easy for too big fish to reproduce. Put the parent fish into the breeding tank according to the ratio of male to female 1:1, and keep the water temperature between 27-29 ℃. After waiting for their mating and spawning, fish out the female. After that, keep the water temperature and water quality, and then fish out the male fish after the eggs hatch. 1、 Choose the parent fish pearl vest, which is sexually mature when it is 10 months old. Generally, male fish with body length of 6cm, red chest, longer abdominal fins and strong body shape are selected as parent fish, and female fish only need to choose the one with larger abdomen. The highest reproductive success rate is the 2-year-old fish, with a length of about 7-8 cm. If it exceeds 10 cm, it is not easy to have small fish. 2、 Generally, the larger fish tank is used as the breeding tank, with the specification of 50 * 40 * 30. Some water and grass should be placed in the tank. Before breeding the pearl vest, the male and female fish should be raised separately. After half a month, they should be put into the breeding tank according to the male-female ratio of 1:1. After a period of time, they will begin to lay eggs and expel sperm. 3、 Water temperature and water quality pearl vest itself is a tropical fish. The water temperature in the breeding tank should be controlled between 27-29 ℃, the pH should be about 6.8-7.2, and the water hardness should be maintained at 6-10. Such an environment will make the parent fish feel comfortable, which is not only conducive to reproduction, but also helpful to the hatching of fish eggs. 4、 After waiting for the spawning parent fish to enter the breeding tank, the male fish will spit bubbles to build a nest, which usually takes 2-5 hours. Then it will start chasing the female fish and complete mating. After the end of the oviposition, the female fish should be removed and put into other water tanks for breeding so as not to be bitten by the male when approaching the foam nest. （ZhenZhuMaJiaYuZenMeFanShi，DuoDaJiuKeYiFanShiLe）
