How to raise a few feng shui fish?

It is advisable to raise fish in nine places. Ancient literati like to make fish-swimming pictures, all of which are based on "Nine Rus". What is Jiuru? According to ancient records, there is a cloud in the Book of Songs: "Heaven will protect you from prosperity, such as hills, hills and rivers, so that you will not grow." If the moon remains unchanged, if the sun rises, if Nanshan lives long, it will not collapse, if pine and cypress flourish, it will never fail. "。 This poem has nine words "Ru", all of which are auspicious words. Because it is homophonic with fish, many people draw nine fish as auspicious pictures with the theme of "Nine Rus". As can be seen from the above, the optimal number of fish farming is nine. But because this fish tank is too small to keep as many as nine, you can keep three or six, because three stands for "three three inexhaustible" and six stands for "six six infinite".
