Koi reproduction needs to meet certain conditions. One of the more important points is the space problem. So, generally speaking, fish tanks are not suitable for breeding. Because the breeding method of Koi is tail flick, it needs more space in this process. If the space in the fish tank is insufficient, it will not help them reproduce, but will lead to water pollution and other problems. Therefore, the fish tank is relatively inappropriate. However, if the size of the fish tank is relatively large and the number of Koi is relatively small, you can try to let them breed in the fish tank. At this time, it is also necessary to meet the age of Koi, the age of male fish needs to be above 2 years to reproduce, and the age of female fish needs to be above 3 years to reproduce. After meeting the conditions of fish age, it is necessary to make the surrounding environmental conditions suitable. The most important thing is the water temperature, which must be above 18 degrees in order to breed.
Koi breeding, it is best to prepare the spawning pond, fish nest and hatching pond. Generally speaking, each spawning pond can be put into 2-3 groups of breeding Koi, so the effect is better. Fish nests are used to attach the eggs laid. After disinfection, the fish nest can be put into the hatching tank, and then wait for the eggs to hatch out. So try not to breed in the tank when the koi.
