Ask a Feng Shui master for advice on where to place the fish tank. I am in the lighting business. I am a male born in the year of Tiger. The store faces north and south. This is the floor plan. Please give me some advice!

From your picture, if you sit north to south, with the door open in the middle, then the vitality of your store is in the east. The fish tank represents wealth and is the thing that activates wealth, so it should be in the front of your store. East. If you are a metal person, then the number of goldfish is 4 or 9. If you are a water person, then the number of goldfish can be 1 or 6.
