? Goldfish are not suitable for polyculture. Although they are gentle and adaptable, they are slow to react and have low foraging ability. If they are mixed with other fish, food will be unevenly distributed. Therefore, it is better for breeders not to keep goldfish together with other fish with strong ability to grab food.
If breeders want to improve their ornamental value, they can choose different kinds of goldfish to mix, which can not only improve their ornamental value, but also avoid the problem of competing for food. The goldfish species more suitable for polyculture are grass goldfish and egg goldfish, because grass goldfish is more solid, survival ability is strong, egg goldfish looks lovely, more ornamental.
are the small ornamental fish that can be mixed with goldfish? Goldfish are not recommended to be mixed with small ornamental fish, because they are different in size. The body length of adult goldfish can reach 20-30 centimeters. If they are mixed with small fish, goldfish may eat small fish. If breeders want to try polyculture, it is recommended to choose lantern fish, guppy, angelfish, fortune fish, etc. Although these are tropical fish, they do not require a high environment, and their actions are more flexible, so it is difficult for goldfish to catch them. Additional, the disposition of these kinds of fish also is more gentle, won't attack goldfish actively. In polyculture, it is better for the breeder to choose some goldfish of the same size to avoid fighting because of the great difference in size.
