No, goldfish can be mixed with some fish, but not all varieties can. Generally speaking, peacock fish is not suitable. First of all, there is a big difference in their body shapes. Some species of goldfish can grow to more than 10 cm, while the length of peacock fish is generally only about 5 cm. Their habits are also different. Guppies have high requirements for water temperature and are sensitive to nitrite in the water. If they are mixed together, it is not easy to adjust the surrounding environment. 1、 Can goldfish be mixed with peacock fish? When raising goldfish, many farmers will consider the problem of mixed culture. However, not all species can be mixed with goldfish. For example, peacock fish is not suitable on the whole. First of all, their body shapes are quite different. There are many kinds of goldfish that can grow to more than 10cm, but the peacock fish is very small, generally about 5cm. If they are mixed, goldfish may threaten the safety of peacock fish. When there is very little food, they may directly eat peacock fish as food. From the aspect of body shape, it is not appropriate to mix the two.
Another is the problem of habit. Peacock fish has high requirements for water temperature. Generally speaking, the water temperature is above 22 degrees, while goldfish is a cold water fish; Moreover, guppies are much more sensitive to nitrite content in water than goldfish. Therefore, from the perspective of habits, it is not easy to adjust the surrounding environment if it is raised together. 2、 Can goldfish be mixed with Koi? Goldfish had better not be mixed with Koi. In terms of size, goldfish are relatively small, and Koi are much larger. If they are raised together, Koi may bully goldfish. Moreover, in terms of temperament, Koi have high activity and are good at competing for food, while goldfish swim relatively slowly and may not be able to grab food. If this goes on for a long time, the growth and development of goldfish will be greatly affected. （JinYuNengHeKongQiaoYuHunYangMa，NengHeJinLiHunYangMa）
