What's the point of keeping a few good fish in fish farming and feng shui fish farming?

1. Raising one, four, and six can make up for your fortune, while raising two, three, and five is not good for your fortune. Raising seven, eight, or nine also means good luck. Seven is a fire, and water and fire are incompatible, but they have mutual affection. Eight is soil, and the soil can be water. Because Eight White is the left auxiliary star, it can be used as a lucky star.

2. The color of fish will also affect the fortune. In geomantic omen, there are gold and white. Because the five elements of gold and white belong to gold, gold can produce water. The colors of fish that are weak in promoting wealth and helping transport are green, cyan, yellow or brown, because the five elements of green and cyan belong to soil, while the five elements of yellow and brown belong to soil, which is unfavorable for wealth and transport. In addition, red is a fire in the five elements, and parallel imports are incompatible, so it is not suitable to raise red fish.
