Hi Master Cecil, I have a gold fish tank in the NORTH sector and a LARGE 400 litres marine fish tank in the NORTHEAST sector of the house. I understand this might not be ideal sectors for the aquariums for this year, but due to the massive size of the Marine Fish Tank, it is not possible to move it every year to the auspicious sector. So, what should I do? Marine Fish Tank - currently in Northeast sector, cannot be moved, i used a lid to cover the aquarium and hang a crystal sphere near the tankGold Fish Tank - currently in the North sector, can be moved if need to, i use a lid to cover the aquarium and place 2 brass dragon near the tank
