guppies can not be raised with highly aggressive fish. For example, tiger fish, goldfish, dragon fish, colorful skirt fish, cross fish and so on. These fish are very aggressive, and if raised with these fish, guppies are likely to be killed or eaten.
Because goldfish are cold-water fish, while guppies are tropical fish. They have different habits and different requirements for the environment, so they are not suitable for raising together. Moreover, goldfish are relatively active, while guppies prefer still water. If raised with goldfish, guppies may be frightened. The resistance of guppies will decrease after being frightened, and they are easy to get sick. In addition, goldfish like to grab food, which will affect the guppy's eating. Therefore, it is not recommended to mix guppies and goldfish in a tank.
guppies and gentle fish suitable for farming together. For example, traffic lights, red lotus lights, triangle lights, and other small lights fish, can be raised together with the guppy. These fish are gentle, elegant, colorful, and are middle and lower fish, guppies are upper fish, mixed with these fish can complement each other, so that the fish tank looks more colorful. However, it should be noted that mixed culture needs to pay attention to the breeding density, to avoid the situation of hypoxia due to excessive breeding density. Generally, about 10 fish can be cultured in 50 tanks, and oxygen pumps need to be turned on in case of high temperature weather.
