It is more appropriate for zebrafish to be mixed with guppy, moonlight fish, mickey fish, penguin fish, Mary fish, traffic light fish, lotus lantern fish, white cloud golden silk fish, red-nosed scissors fish and cherry lantern fish. Zebrafish are mild in character, weak in aggressiveness and attack power, and they have no sense of territory. In addition, they are small and exquisite, and like to swim constantly in the fish tank, so they are very suitable for polyculture with other fish. These kinds of fish have strong adaptability to the environment, and their requirements for the environment are not high. When they are mixed with zebrafish, there is generally no big conflict.

1. There is plenty of space: Although zebrafish is small in size and does not require high space, breeders should also pay attention to the density of breeding. Because the density is too high, it will lead to poor water quality and lack of oxygen, so breeders need to decide the number of breeders according to their size.

2. Environmental stability: Although zebrafish and polyculture fish have low requirements for the environment, they are sensitive to environmental fluctuations. When raising artificially, it is necessary to keep the water temperature and water quality stable, so as to avoid sudden changes in the environment and make them uncomfortable.

3. Regular oxygenation: Zebrafish has a high demand for oxygen, and breeders need regular oxygenation every day to ensure sufficient oxygen in water. If there are a large number of mixed fish, the oxygenation time should be extended appropriately.
