Does your family care about Feng Shui? If you don't care, you can just ignore it and just keep it as you like~~~~
If you care about it, or if your family members are doing business and care more about it, there is still something to say about the color, quantity, and variety of the fish; There are several types, the quantity of each type, the color matching, etc. are very particular~
I personally also keep fish, the number is 7, (silver dragon, fortune and parrot) remember, The popular saying is: raising single fish or not raising pairs is fine~~ Especially white tropical fish are said to pay attention to Feng Shui (they are Feng Shui fish). If you just raise cold water fish, goldfish, etc., don’t worry too much. ~
Hope it can help you~~
