China has a saying that the Ninth Five-Year Plan is respected. Therefore, according to Feng Shui culture, it is appropriate for koi fish to raise Kyubi no Youko, which has extremely noble implications; In Feng Shui, Vulpix Dante stands for "good luck every year", and five tails are red and white, which means "five blessings".

In China's traditional scholarship, the highest number of "Nine as Yang" has extremely lofty meaning. In Feng Shui, it is considered the most auspicious and lucky to have nine koi fish with a right star on it, which can make the family smooth and rich.

In addition, the saying that "three sheep open Thailand" and "Shuanglong play in the water" is also widely circulated. Therefore, koi fish is full of geomantic omen, and it is best to raise koi fish three, six, five, nine and two tails at home.

Methods of raising koi fish: First of all, we should pay attention to the environment of raising koi fish, keep the water temperature well, and control the temperature of fish farming, generally at 2 to 30 degrees Celsius. If it is a new koi fish, pay attention to the water to adapt to the temperature. Remember to add a heating rod if the temperature is too low in winter. Water should also be changed frequently to keep the water clean. Remember to wipe the fish tank and clean it thoroughly when changing water.

Furthermore, koi fish is an omnivore, feeding many things, such as fish feed, worms, crab meat, bean cakes and vegetables. Of course, when feeding, the food should be made into fine particles, which is convenient for koi fish to eat. Don't feed too much, or the fish will not hold up.
