Fish plays an important role in Asian culture. Therefore you will find a lot of art and other works of display which uses the form of fish such as koi or goldfish in these cultures. Similarly feng shui gives a lot of importance to fish tanks in home. But there are specific positions to keep a Feng Shui Fish Tank to bring in health and prosperity; whereas there are other locations that you should avoid keeping any water source. It’s not necessary to have a large fish tank in your room, unless you have a large living space. It’s important to create a balance in your room. Do not clutter your room with a large fish tank if there is limited space. This goes against the feng shui principles.
