2, the fish tank should not be too big: too big fish tank will store too much water, too much water will lack the risk of flooding. From the perspective of geomantic omen, water is important, but too much and too deep is not appropriate, and the fish tank is too high above the eyes when adults stand up, so the fish tank in the living room should not be too big and too high, especially in the small living room.
3, the fish tank can not be placed under the financial position, because "God is in the water", putting the statue of God of Wealth on the fish tank is equivalent to committing a taboo of Feng Shui, which is not conducive to family fortune.
4, the fish tank can not be placed behind the sofa, because the back of the sofa is called the backer, but the water has a lot of instability, and it is unlucky to use the fish tank as the backer behind it.
