Matters needing attention in polyculture

1, feeding habits: the food of ornamental fish can be divided into live food and feed, and fish with different feeding habits should not be mixed. If polyculture occurs, the water quality will deteriorate because of different foods, and carnivorous fish are aggressive, which is easy to bully fish that eat feed and will also cause harm to fish.

2. Personality: When mixing different fish, we should also consider the personality of the fish. Fierce fish must not be mixed with docile fish, otherwise it will inevitably cause harm to the weak side. For example, the species of large gallnut is fierce, and few other fish can be polyculture except other gallnut, so the problem of polyculture should also understand the aggressiveness and polyculture degree of fish.

3, body shape Whether it is the same kind of fish or mixed species of different kinds of fish, we must pay attention to the difference in body shape. The law of the jungle in nature doomed the strong to prey on the weak, so the difference between body shape and physique is too great, so it can't be mixed, otherwise the weak will face life. Danger. For example, peacock fish and map fish are mixed, and you may not even find a peacock.

4, temperature polyculture taboo cold water fish and tropical fish polyculture, this is the most basic knowledge. But experienced players can still achieve a certain balance.

Some special ornamental fish can only be raised singly, if they are mixed, something will happen. So to avoid this kind of thing, it is necessary to remember that those fish that can't be mixed, including pike, S-genus water tiger, Lohan, red dragon and golden dragon, can't be mixed or try not to be mixed.
