The fish tank is on the shoe cabinet at the door. Is feng shui good?

Geomantic speaking, the fish tank must be placed in the position of prosperous wealth, otherwise it will be refunded or even broken if it does not make money.

When you describe whether the location of the porch is a financial position, the safest way is to ask a Feng Shui master to make a field survey for you.

As for "shoe cabinet below, fish tank above", there is no problem.
