As a symbol of Feng Shui fish, koi fish are considered auspicious if you keep a few of them.

To decide how many koi fish are appropriate, you should consider the following three factors:

The first is the size of the fish tank. If the fish tank space is too small, it will not only affect the viewing effect of the fish, but also may cause difficulties for the growth of the fish. An overcrowded environment may also greatly increase the possibility of the fish getting sick.

The second is Feng Shui. Generally speaking, the following numbers are available for reference: Jiu Jiao - the magic number believes that nine is one of the poles of the number. After the number reaches nine, it will unify and start again, so nine is the largest number. In addition, the "Qian" hexagram in the "Book of Changes" says that the flying dragon is in the sky, which refers to a state when the line number is nine or five. In addition, we can often see "nine fish pictures" in koi paintings, which fully illustrates that nine koi are a very good choice. In addition to the nine numbers, we can also choose numbers 2, 3, 5, 6, 7, 13, 17, 18, 19, etc. as a reference.

Finally, you need to consider the overall budget for Feng Shui layout.
