There are two different views on the location of fish tanks in geomantic omen.
1 the fish tank should be placed in the prosperous position, because the water in the fish tank is endless, so if the fish tank is placed in the prosperous position, it will drive the prosperity in that direction and improve the wealth.
The fish tank should be placed in the descending position, because it conforms to the saying of "throwing water into the zero hall", which refers to the descending position of losing luck. According to the geomantic theory, introducing water into the lost position can turn disasters into blessings and all misfortunes into good luck. This statement is more credible, because if you put the fish tank in the position of Wangcai, it will violate the taboo of "putting the god of wealth in the water", and it will undoubtedly push the god of wealth of Wangcai into the water and then meet the water of wealth.
