Can the feng shui of raising fish at home be improved?

In view of the fact that fish farming can change the feng shui of houses, I personally think that the real feng shui is not to put one or two things to promote prosperity! ! If that's true, are there any poor people in the world? Raising fish at home can't change anything, and it can't improve wealth! That's a fake feng shui that deceives people. If fish farming can make a fortune, the owner of a fish shop should be the first to develop!
