In addition, it is best to choose a round fish tank with a small mouth and a big belly. The round fish tank belongs to gold, which produces water and aquatic money, so it has the function of prospering wealth. Moreover, from the perspective of air breathing, a round fish tank with a small mouth and a big belly is conducive to gathering gas, and wealth can be gathered together, which will not make it go up in smoke.
Fish itself has its five elements, and we mainly distinguish them according to the color of fish. For example, goldfish belongs to gold, so golden water and goldfish are more prosperous. Moreover, snakehead has better reproductive ability. Black is water, and water is the main wealth. Raising snakehead can naturally help you make a lot of money. Yellow croaker belongs to soil, and the water and soil are in harmony, so it has less ability to make money. Similarly, the earning power of red and green fish is relatively weak.
Some geomantic omen believe that the number of fish is also a factor related to its earning power. Yang 1, 6, and 9 are all lucky numbers with strong ability to make money, 2, 3, and 5 are all numbers that are not conducive to fortune, and the rest are medium-fierce.
Also, there is a saying in Feng Shui that "water draws into zero hall". Zero hall refers to a relatively declining or unlucky position in fortune, and the introduction of water into zero hall can bring good luck. Therefore, keeping a fish tank in a place with weak discrimination can bring good luck!
