In the traditional culture of China, goldfish is regarded as a symbol of good luck, so many people like to keep goldfish at home to bring good luck and good luck. However, there is no fixed regulation on the number of goldfish, depending on personal preferences and the conditions for raising fish.

Generally speaking, it is common to keep 3 to 5 goldfish at home. Such a quantity can make goldfish have enough space in the aquarium, and at the same time, it will not cause overcrowding.

However, the number of goldfish still needs to consider the following factors:

1. fish tank size: goldfish need to have enough swimming space, so the appropriate number should be determined according to the size of fish tanks.

2. Water quality management: Goldfish will produce waste, and too many goldfish may lead to water quality deterioration, which increases the difficulty of aquarium maintenance.

3. Fish farming experience: If you are an experienced fish farmer, you can consider raising more goldfish. However, if it is the first time to raise fish, it is recommended to start from a small quantity and gradually increase it.
