The first is to choose the parent fish. You need to choose the map fish with suitable body shape, color and constitution. Then put them in a specially prepared breeding tank to keep the water temperature at 26-28 degrees and the pH value between 6.5-7.5. The female ovulates and the male inseminates. The fertilized egg can hatch successfully after 2-3 days. In a week or so, the small fish can move by themselves and look for food everywhere. 1、 How to breed map fish 1. Parent fish selection: first, to breed map fish, you need to choose the right parent fish. Specifically, we should choose the map fish with appropriate body shape, body color and physique. The body shape should be moderate, the body color is good-looking and has the characteristics of variety, and the physique should be healthy.
2. Breeding tank insemination: after selecting the parent fish, it is best to prepare a breeding tank to put them in. The specification of breeding tank can be 60 * 45 * 45 cm. After putting them in, the following conditions need to be controlled. For example, the water temperature needs to be kept between 26-28 degrees, the pH value of water is better between 6.5-7.5, and the dissolved oxygen should also be noted, not less than 6 mg / L. Under suitable conditions, the female fish will row the eggs to the surface of the stone, and the male and female will inseminate. This process will take about three hours.
3. Hatching: after the process of insemination, the next step is hatching. Specifically, when various conditions are suitable, it can hatch successfully in about 2-3 days. In another week or so, the small fish can move freely. In the process, the parent fish may always be next to the small fish to protect them. However, in order to prevent them from accidentally eating the small fish, they can be fished out after insemination.
4. Maintenance of small fish: after small fish can move freely, they can be fed. The food that can be fed is harvest insects or Daphnia, which can be fed four times a day. After about half a month, you can feed red insects and other feeds. 2、 How often can map fish reproduce? Map fish can reproduce many times a year. If the conditions are suitable and the constitution of map fish is good, it can reproduce 3-4 times a day. Even if the conditions are not so good, it can reproduce about twice a year. They breed mostly in summer and autumn. （DeTuYuZenMeFanShi，DuoChangShiJianNengFanShiYiCi）
