The formula to calculate the appropriate tank size for goldfish is:
\[ \text{Tank Size} = 20 + 10 \times (G - 1) \]
Where:
A goldfish tank size refers to the capacity of the aquarium where goldfish are kept. The size of the tank is crucial for the health and well-being of the goldfish as they require ample space to swim and grow. The recommended minimum size for a goldfish tank is 20 gallons for the first fish and an additional 10 gallons for each additional fish. This allows for proper filtration, reduces the concentration of waste, and provides enough oxygen for the fish.
Let's consider an example:
Using the formula to calculate the tank size:
\[ \text{Tank Size} = 20 + 10 \times (3 - 1) = 40 \text{ gallons} \]
This means that for 3 goldfish, the appropriate tank size is 40 gallons.
