I have implemented many of the Diamond Feng Shui cures and activations, but I'm still struggling in a couple of areas. I understand that an aquarium is one of the activations for the North direction, and that activating the North is part of the Power Diamond Facet. Does this mean that I can place the aquarium anywhere in the North area of my home (as marked on the floorplan)? Also, are there any rules in Diamond Feng Shui regarding the number and color of fish in an aquarium? I have heard that a true "feng shui" aquarium should have 8 gold fish and 1 black fish.Thanks!
