What's feng shui about fish tanks?

Nowadays, people like to raise fish in the house, and fish tanks are like water. In ignorance, it's best not to place fish tanks blindly, otherwise it's not worth the loss, but counterproductive.

In feng shui, "the mountains are fixed and the water pipes are rich." Where is the house suitable for watching water? If there is water, it will benefit money. Where it is not suitable to look at water, there will be a loss if there is water. And these need to be laid out according to the sitting direction and construction time of the house, which is not something that ordinary people can do. There are also many taboos in the placement of fish tanks, such as not putting them in the bedroom, not in the kitchen, not under the idol and so on. Because fish like dark environment, it is difficult to survive if there is plenty of sunshine. Once a fish dies, it is also an indirect killing. But is it necessary to do feng shui?

If you really want to raise it, then put it in the financial position, that is, the entrance is inclined at 45 degrees. But this statement lacks certain accuracy.
