? Koi and goldfish can be mixed. First of all, they do not have high requirements for water quality environment, and the water quality environment they need is similar, so they can not be polycultured because of different conditions suitable for survival. They are all suitable for living in weak alkaline soft water at 21-28 degrees Celsius. Secondly, they are omnivorous and carnivorous animals, and the bait they eat can be the same, thus avoiding the difficulty of feeding.
When polyculture, it should be noted that although Koi is mild, it likes to grab food. This may cause the goldfish to be unable to eat food, so make sure that the amount of feeding is adequate. However, koi are slightly larger than goldfish, and may eat or bite goldfish, causing them injury. Therefore, when raising, it is necessary to put enough water plants in the fish tank to provide a place for goldfish to hide.
with Koi? Koi can be mixed with mild fish, such as goldfish, topmouth gudgeon and so on. It should be noted that Koi is a cold-water fish, and it is better not to mix with tropical fish. Although there may be an overlapping range of water temperatures to which they can adapt, their habits are not the same. You can't take care of both if you mix them, so it's better to mix Koi with some cold-water fish with similar size and habits.
