My family wants to buy a round fish tank. Where is the best place?

Fish tanks are generally not placed in bedrooms. Generally speaking, the living room is better, and the cylinder mouth should be rushed up along the door. If you bring an air pump, the air inlet should be facing the door, which is intended to suck in wealth. Fish farming can make money, but don't put it in the southernmost part of the room. The south is fire, opposite to water. This feng shui is not good. You can put it in the corner of the living room and porch. In front of the hall, facing the door, just right.
