Careful consideration should be given to mixing koi and goldfish. Although koi fish can be mixed with goldfish, it is best done by experienced breeders. It is not recommended for novices to try.
Koi swims fast and likes to compete for food; goldfish not only swim slowly when looking for food, but goldfish are not good at competing for food.
Koi carp are relatively large, while goldfish are relatively small. In the mixed culture process, fights will inevitably occur when fighting for food during feeding, and the goldfish will inevitably be accidentally injured in the end. Sometimes koi will eat goldfish. So be especially careful when mixing them.
If you must polyculture, you can choose suitable fish for polyculture. When selecting, you must understand the living characteristics of the fish to be polycultured. You must be cautious about aggressive fish and choose suitable fish. For mixed-breeding objects, special attention should be paid to separating them in time if fights occur during the mixed-breeding process.
Extended information:
The original variety of koi is red carp, which is said to have originated from Longzhou koi in Guangxi, China, Xingguo red carp in Jiangxi, and golden carp in Hangzhou, Zhejiang. After long-term artificial selection and cultivation by the Japanese, it became the current koi. In terms of color and pattern, there are now more than 100 varieties in 13 categories. According to historical records, around 1804-1829, Japanese nobles first put koi in ponds for viewing.
Koi has a strong personality and a vigorous swimming posture. He has a calm and fearless demeanor, and will not struggle even if he is placed on the chopping block. At present, koi carp is loved by more and more people in China and is known as "good luck fish", "feng shui fish", "living gem in water" and "king of ornamental fish".
