2. Health. If you are in the south and the indoor humidity is high, it is recommended not to do so, which will aggravate the humidity and be bad for your health. If it is in the north, there is no such problem.

There is a saying that there is a fish tank in the bedroom and the husband and wife have an argument. I think it's best not to raise fish in the bedroom, because the size of the aquarium is different from that of an ordinary fish tank, and it emits a lot of water vapor, which will increase the indoor humidity, easily breed mold and lead to biological pollution.
