, if you want to raise koi carp big and fat, first of all, you should pay attention to the food you feed. When koi carp is in the golden period of development, the breeder had better feed them some high-nutrition, high-protein food. Shrimp, bloodworms, mealworms, mealworms and so on are more common. Although these highly nutritious foods can promote their development, breeders also need to match some plant feed and synthetic feed to ensure their nutritional balance.
Secondly, we should prepare a bigger fish tank for them, because the size of Koi is bigger, if the fish tank is too small or the feeding density is too high, it will affect their growth and development.
Furthermore, it is necessary to ensure the stability of the surrounding environment, because although the adaptability of Koi is strong, they are more sensitive to changes in the environment, if there are frequent environmental mutations, it will also affect their growth and development.
Finally, it is necessary to ensure adequate oxygen for breeding. Koi carp need a lot of oxygen. If they lack oxygen, they can not grow well.
color? If you want to make koi with bright color, you should feed more food rich in astaxanthin and enhance light at ordinary times, so as to promote their vitamin synthesis. If the koi are kept indoors, led lights can be installed to help them add color.
