You should also pay attention to raising fish in the living room, and don't destroy the feng shui in the living room. Don't put the fish tank behind the sofa. From the perspective of geomantic omen theory, it is not reliable to rely on water as the backing. Because of the impermanence of water, it is difficult to rely on it as a backer. Put the fish tank behind the sofa, and the whole family will feel less reliable than the mountain every day, which will affect the stability of the house's fortune. If you put the fish tank next to the sofa, it will not cause great obstacles to the house traffic and geomantic omen. At the same time, remember not to collide with the stove. The fish tank carries water and the kitchen stove makes a fire. Because fire and water are incompatible, if the fish tank in the living room and the kitchen stove are hedged, it will affect the health of the family from the perspective of geomantic omen. Also, the fish tank can't be placed under or beside the altar, because the altar is also a heavy object. The fish tank should try to avoid being placed in a straight line with the altar to avoid collision. At the same time, the fish tank should not be placed under the god of wealth. According to feng shui, the god of wealth belongs to wealth, and the god of wealth should be placed in a prosperous position, while the fish tank should be placed in a declining position, so it cannot be put together. If put together, one of them must be wrong.
