? Koi breed. They usually breed in spring. As long as the water temperature reaches 18-35 C, they can breed. Koi is a tail-flick breeding, which requires a larger space. If it is raised in a fish tank, the number of breeding times may be reduced a lot.
? 1. Water temperature: Koi generally breed in spring, as long as the water temperature can reach 18-32 ℃, they can breed. However, the most suitable temperature for their reproduction is between 22 and 30 degrees Celsius. It is suggested that the breeder should keep the water temperature at 25 degrees Celsius to ensure the stability of the water temperature, which can effectively promote the reproduction of Koi.
2. Space: Koi need more space to breed, because they are tail-flick breeding, if they are raised in a fish tank, it is basically impossible to breed successfully. If you want koi to breed, you need to prepare a large spawning pond and hatching pond for them. If there is no condition to prepare the spawning pond and hatching pond, the breeder can prepare a larger tank for the breeding of Koi.
3. Water quality: Koi likes weak alkaline water. It is better for the breeder to control the PH value between 7.2 and 7.5. Especially in the early stage of reproduction, it is better to control the fluctuation of PH value not to exceed 0.1-0.5. To ensure that the water quality is fresh and stable, it can also promote the reproduction of Koi.
