According to the characteristics of your room, there are two schemes: first, if you change the vat in the future, you can put it between the porch and the imperial concubine couch, that is, where the clothes rack is hung, and become a screen to separate the porch and the living room softly. One of the great advantages of this scheme is that you can make money by entering the door and seeing water! The disadvantage is that the side of the person sitting on the sofa is water, not a mountain, which is slightly unstable, but fortunately there is no back water. Another scheme is that if you don't change the fish tank, you can put it in the bonsai position on the south side of the TV cabinet, and the reason is the same. I saw the water as soon as I entered the door. Great!
Other places do not need to be considered, such as bathrooms and bedrooms, while fish farming on the balcony is ok, but it is not respected in geomantic omen: raising water outside the house will lead to the leakage of wealth.
As for the number of fish, you can refer to: rat, pig: 1 or 6.
Tigers and rabbits: 3 or 8
Snakes and horses: 2 or 7
Monkey, chicken: 4 or 9 or 5
Dragon, dog, cow and sheep: 5, 10, 4, 9
Gold is the best color, and red is also good.
The above suggestions, personal views, refer to the implementation.
