Specifically, to choose a map fish with suitable body shape, body color and physique, the body shape should be moderate, the body color should be good-looking and have the characteristics of the variety, and the physique should be healthy.
2. Breeding tank insemination: After selecting the parent fish, it is best to specially prepare a breeding tank to put them in. The size of the breeding tank can be 60 * 45 * 45 cm. After putting them in, the following conditions need to be controlled, such as water temperature needs to be maintained between 26-28 degrees, water PH value is better between 6.5-7.5, dissolved oxygen should also be paid attention to, not less than 6 mg per liter. Under the right conditions, the female will release the eggs to the surface of the stone, and the male and female will fertilize them. This process will take about three hours.

In a week or so, the fish will be free to move. In this process, the parent fish may always be beside the small fish to protect them. However, in order to prevent them from accidentally eating the small fish, they can be fished out after fertilization.
4. Maintenance of small fish: After the small fish can move freely, they can be fed. The food you can feed is Artemia or Daphnia, which can be fed four times a day. After about half a month, it can be fed with red worms and other feeds.
Map fish can reproduce many times a year. If the conditions are suitable and the physique of map fish is good, they can reproduce 3-4 times a day. Even if the conditions are not so good, they can reproduce about twice a year. They breed mostly in summer and autumn.
