To solve the fading problem of golden koi, it is necessary to rest, keep the temperature constant and supplement some nutrition. There are many koi carp of this variety, which are basically yellow as the background color, but other parts will have other colors. It is mainly distributed in Japan, which can adapt to a slightly lower temperature environment. At the same time, it has a miscellaneous diet, can eat a lot of things, and likes slightly alkaline water quality. The ph is generally between 7.2 and 7.5.

1. Fish tank: When breeding golden koi, the first step is to prepare the fish tank. The size of golden koi is relatively large, so an important aspect when choosing a fish tank is that the fish tank should be large enough. It can also be farmed in cement ponds.

2. Oxygen: Oxygen is also an important factor in the breeding process. Because the golden koi is very large, their requirements for oxygen are relatively high. It is necessary to ensure the amount of dissolved oxygen in water. Therefore, the water quality should not be too dirty, otherwise the dissolved oxygen will decrease, so it is necessary to change the water regularly. Furthermore, some green plants can be properly placed in the fish tank, which can release some oxygen. If necessary, you can also use an oxygen pump to supplement some oxygen.

3. Water temperature: The water temperature should also be paid attention to. Although golden koi has good adaptability to water temperature and can endure lower temperature, try not to be lower than 10 degrees in the process of breeding, otherwise it will affect their appetite and activity.

4. Feeding: Providing adequate nutrition through feeding is an important step. Golden koi likes to eat animal feed, and it is a living animal, such as water fleas, water earthworms and so on. It is better to feed it 1-2 times a day. Their appetite is at its peak from June to September, when they can be fed twice a day. The rest of the time, you can feed it once a day.
