Raising different numbers of fish is actually different in feng shui:
Keep a fish: a white wolf star, and the five elements belong to water. Good luck.
Keep two fish: two black giants, and the five elements belong to the soil. Two black stars represent disease symbols. Unfavorable to wealth.
Raise three fish: three blue trees hide stars, and the five elements belong to wood. Sambo stars represent right and wrong. Unfavorable to wealth.
Raise four fish: four green stars, also called wenchang star, and the five elements belong to wood. Although drainage, Siqing is a satellite, so it is also auspicious.
Raising five fish: Huang Wulian is revitalized, and the five elements belong to the soil. Soil and water are not conducive to wealth.
Raise six fish: six white and five curved stars, and five elements belong to gold. Gold produces water, which is beneficial to wealth.
Raise seven fish: seven stars and red star Pojun, and five elements belong to gold. Gold produces water, which is beneficial to wealth.
Raise eight fish: eight white left auxiliary stars, and five elements belong to soil. Earth and water, but 800 is the left auxiliary wealth star, which is beneficial to wealth.
Raising nine fish: nine purple has a right star, and the five elements belong to fire. Nine purple is the lucky star of Youbi, which is conducive to wealth.
However, besides keeping a few fish, the most important thing is to see if you need water in your life. If you don't need water in your life, you don't need to raise fish.
