Usually think about what kind of fish tank you need to keep first. Straw vat, goldfish bowl and dragon fish bowl are all different. Generally, the depth of the straw tank and the width of the fish tank are 40-45 cm, and then metal halide lamps should be used. Generally, the water depth of a goldfish bowl is less than 40 cm, and then only one variety of gold can be raised. The water depth of the dragon fish tank is generally 65-70 cm, the length is greater than 1.5 m, and the width cannot be less than 65 cm. The fish tank determines the size of the bottom cabinet.
The actual waterline of the fish tank must not exceed the height of the main family members, otherwise it will violate the taboo of "no top water" or "shower head water", which will turn the family fortune away and be suppressed.
In addition, if you pay attention to Feng Shui, you can refer to Lu Banchi (also called Ding Lan ruler and Feng Shui ruler) to determine the specific size.
