Does it matter if there is no fish in the fish tank at home?

I remember that Master Wen Ze added in the first Feng Shui exhibition that fish are kept in fish tanks because there are fish in them, just to make the water move, not become stagnant water. Water also gathers wealth, but it must be running water, but the fish tank should be placed in the position of making money. If there is no fish and water in the fish tank, it will not have much impact on Feng Shui.
