"Ruyi" is an auspicious item and has nothing to do with faith. To pray for peace and all the best, there is no problem in placing it at the door of the living room. In addition to decorating the living room, some decorations also have the function of warding off evil spirits and conducive to home feng shui. For example: horns, Buddha statues, crosses, etc. all have different functions. In addition to being a decoration, setting up a fish tank to raise fish in the living room can also bring wealth and lively atmosphere to the whole family. One thing to note is that when choosing fish, fish with bright colors and long life should be the best, and they should be taken care of carefully. The fish kept in the fish tank must not make them sick or die, and the water must be kept clear. If the fish in the fish tank dies or becomes sick, or the water is dirty and smelly, it will be worse than not placing a fish tank at all.
