In feng shui, fish tanks are full of water, which belongs to water. It is ok to put the fish tank at the door, because it can not only decorate the porch, but also play the role of shielding the screen, so that the gas field at the door will fluctuate and will not remain the same. But it's best not to face the door directly. If the fish dies, it will be unlucky. Better lean towards the gate.
In addition, the fish in the fish tank are full of vitality, which can play a positive role in feng shui at home, but it is not a place that can be seen at a glance. If you put the fish tank where you can see it as soon as you enter the door, your wealth will change with your good mood every day. If you are in a good mood, it's okay. If you are in a bad mood, the fish tank will absorb this bad luck and make your fortune worse.
Precautions:
1, when buying a fish tank, it is best not to buy a big fish tank. The fish tank should be placed on the table, preferably not over the chest, and the water in the fish tank should not exceed the neck. Because when the water level in the fish tank is too high, the fortune at home is not good and the gas field is suppressed.
Secondly, don't put the fish tank behind the back of the chair. In geomantic omen, it is not good to regard water as a backer. The nature of water is changing at any time, and it is not very stable. Relying on water will affect the fortune of the house and cause turmoil.
