It's good to keep a few silver dragons in a fish tank. Some people say that only one can be left. Why?

How many arowana should be raised from three aspects: geomantic omen, aquarium and polyculture.

First, feng shui

As a feng shui fish, 1 must pay attention to the quantity of farming. It is generally believed that nine is the best, and "Nine Fish" symbolizes good luck. But if the fish in Kyubi no Youko can't fit into the ordinary aquarium, you can keep six or three, which means "six or six are infinite" and "three or three are inexhaustible".

There are the following words on the five elements: one-a white water, prosperous wealth. Six articles-six white gold and water, thriving.

Wei Zi said: One, three, five, six, seven and nine are auspicious numbers.

The river map says: One and six are water, two and seven are fire, three and eight are wood, and four and nine are gold.

To sum up the following points, one, three, six and nine are auspicious feeding amounts. Of course, from the perspective of feng shui, how to raise a few arowana can't be concluded, and it also has a lot to do with the date of birth of the owner.

Second, the aquarium.

The size of the aquarium is one of the factors that must be considered when raising several arowana.

1 arowana grows rapidly, and the aquarium should generally be kept above 140 cm. If you want to raise more, then the aquarium must be enlarged. Generally speaking, a liter of water raises one centimeter of fish, and you can know how many ornamental fish you need to raise through simple calculation.

Third, polyculture

1 raised a dragon but not a pair. There is only a singular number of fish farming, in order to contain the dragon in the tank and avoid the fight caused by the sneak attack of the third party.

If it is an even-numbered hybrid from the beginning of the silver arowana fry, it is ok to consider only the hybrid except the geomantic omen, but if it is an even-numbered hybrid in the middle, it is easy to have a fight.
