The feng shui fish tank is placed at the bottom of the stairs.

The fish tank is a decorative thing, and the focus of your home should be this fish tank. Isn't it a little wasteful for you to put it under the stairs?

I suggest changing the dining table to a smaller one. Usually you don't need such a big table at home. Then put the fish tank on one side of the table, just separating the dining room from the living room.

If you see fish swimming around while eating, is there an impulse to catch one and eat it?
