Can you put the dragon anywhere in the fish tank? What are the benefits? How about Feng Shui?

Hello, the dragon is not anyone's constellation. The five elements of the dragon belong to the earth, and the five elements of the fish tank belong to the water, so the dragon ornaments can't be put on the fish tank! Dragon and phoenix in one. If you want to put the dragon ornaments, you should put them in the middle of the house. There cannot be five lines of water in this position! Thank you, please adopt!
