Second, the shape of the fish tank is also closely related to the geomantic theory of raising arowana:
1, round aquarium, the five elements belong to gold, and gold can produce water, so it promotes wealth.
2, square aquarium, the five elements should be soil, soil, water, so it is not appropriate to choose a square aquarium for arowana.
3, rectangular fish tank, the five elements are wood, born with water, so it is also possible to raise arowana.
4, hexagonal aquarium, five elements belong to water, is the most suitable aquarium shape.
5. Triangular, octagonal or polygonal aquariums, with five elements belonging to fire, should not be chosen as the aquarium of arowana.
3. Quantity: From the perspective of geomantic omen alone, it is generally believed that Kyubi no Youko is the best quantity for fish farmers, but if Kyubi no Youko can't fit in general fish tanks, you can raise Vulpix or Sanwei, which means "66 infinity" and "33 inexhaustible".
