Koi breeding, first of all to control the density. It is not correct to breed too many Koi in small tanks, which will cause them to grow poorly. Generally speaking, if the specification is 60 * 30 * 15 cm tank, the number of Koi can be raised is about 6, not too much.
Koi breeding, to maintain the water quality has been appropriate is also very important. Therefore, it is necessary to change water regularly and clean up the impurities in the tank in order to provide a clean environment for the growth of Koi. Specifically, the frequency of water exchange can be controlled in 3-7 days, the water exchange in summer needs to be more frequent, and the interval in winter can be slightly longer. Every time you change the water, you can change one third. In order to ensure that the water temperature does not change dramatically, it is necessary to control the flow rate of water and slowly inject new water.
Another important issue is feeding, which requires normal feeding methods. First of all, choose good food, Koi is omnivorous, so try not to use only one kind of food, so nutrition may be insufficient. It can combine plant and animal foods, such as vegetables, earthworms, red worms and so on. Can be fed once or twice daily, once in the morning and once in the afternoon.
When breeding koi, it is necessary to provide a certain amount of illumination every day. Especially when there are other plants in the tank, they need to provide light to allow them to photosynthesize. However, in summer, considering the strong light, they can be properly shaded.
In winter, special treatment can be carried out to let the koi pass the winter and put them in a pool with water temperature of 5-10 degrees. At this time, the feeding frequency is not too much, and it can be fed once every 3-5 days.
