In fact, you can raise a few fish. The number of fish depends mainly on the indoor environment, the size of the fish tank and the species of fish. If the indoor environment is limited, it is not suitable to raise too many fish.

How is the number of fish affected?

1. Rectangular aquariums are generally used to raise fish at home. This kind of water tank is generally small in size. It is best not to raise too many fish. The amount of fish should be less but not too much.

2. If the individual fish is relatively large, the number of fish should be smaller.

3. When the water temperature is low, you can raise more, and when the water temperature is high, you need to raise less.

4. Some fish cannot be kept alone, otherwise they will hide in the aquatic plants because they are timid. However, if they are betta fish, they need to be kept separately.
