How many goldfish should I keep?

The appropriate number of goldfish to raise is generally 3-5. When raising goldfish, you need to consider factors such as water quality, tank size, and the space for the goldfish to grow. If the fish tank is small, raising too many goldfish will cause the water quality to deteriorate and affect the growth and health of the goldfish. Each goldfish requires at least 20 liters of water volume, and larger tanks can accommodate more goldfish. At the same time, goldfish need enough swimming space among themselves. Too many goldfish will cause crowding and competition for food.

Therefore, raising 3-5 goldfish can maintain better water quality and stable fish stocks
