What feng shui fish am I suitable for? How many are there? PS: My home is a small fish tank.

The number of fish is preferably 4, 7 or 9. 4 and 9 are the innate gold number, and the total gold number after 7 days. Generally buy red, white and black as auspicious colors, such as 6 red, 1 black and so on. Don't buy fighting fish, and don't put the fish tank under the idol, in the kitchen or near the appliances. Bedside will make fish and you worry.

As long as the color is right, no matter the size, for example, the red arrow is black, and the white-haired globefish is a black peacock. ...

Also, you can buy the following book, which is very detailed (I typed it above)
