Fish tanks should generally be square or round, whether rectangular or square, perfect round oval, large or small, are all suitable fish tanks. But don't choose irregular fish tanks such as triangles, because triangles belong to fire, which will lead to incompatibility and conflict.
Nowadays, many people like oversized fish tanks, which contain all kinds of fish, which can be called a scene of the room at home. Have you ever thought that the water level in a fish tank should not exceed the height of an adult's heart? If the heart is like fire, it will also cause a situation where water and fire are incompatible.
The fish tank can't be placed under the fairy, and it can't be facing the stove. Both of them are fire, which will also cause incompatibility and affect the family feng shui pattern.
Don't put the fish tank in a dark and humid place where there is no sunshine all day. The water released from the fish tank will make the already dark and humid environment even wetter and colder. The fish tank should be placed where it sees the sun.
Fish should be replaced immediately after death, and a few dead fish should be replaced, because fish farming brings wealth, and fish will be ruined after death, so it should be replaced in time.
The above is the taboo of fish tank geomantic omen.
