Raising a few fish mainly depends on how big the fish tank is. The bigger the fish tank is, the more fish can be raised. If the number of fish exceeds the limit of the fish tank, it will lead to no space for the fish to move, affecting its growth, and even harmful to its health. And the more fish, the greater the consumption of oxygen, if the oxygen in the water is insufficient, it will also lead to the death of fish due to hypoxia and other factors.
1. Similar body shape: The body shape of polyculture fish must be similar. In the world of fish, it is immutable for big fish to eat small fish. Therefore, if there is a difference in body shape, small fish cannot survive from the mouth of big fish. Of course, in addition to body shape, personality is also very important, some fish are aggressive, and are not suitable for mixed culture.
2. Similar habits: In addition to the similar body shape, the habits of the fish should also be similar. After all, they are raised in the same environment. If the requirements for water quality and temperature are different, there will always be one party that cannot be raised well. Therefore, if the current fish like acidic water quality, mixed fish should do the same.
3. Sufficient space: Polyculture fish must provide sufficient space, because some fish will have territorial awareness, if the territory is violated, they will attack, and sufficient space can provide a certain safe distance, avoid frequent territorial violations, but also let the fish have a place to escape.
4. Feeding: The polyculture fish must be fed. If the fish often feel hungry, especially some carnivorous or omnivorous fish, it is inevitable to attack other fish. However, after feeding, the probability of this happening will be greatly reduced.
