Are you thinking about keeping goldfish as pets, but you’re not quite sure how many you can safely house in a 60-gallon tank?

A 60-gallon tank is a great size choice for goldfish enthusiasts, offering ample swimming space and room for decorations.

In this article, we’ll explore the ideal number of goldfish you can keep in a 60-gallon tank, ensuring a happy and healthy environment for your aquatic friends.

Determining the Right Number of Goldfish

The number of goldfish you can keep in a 60-gallon tank depends on several factors, including the adult size of the goldfish and their space requirements.

Goldfish can reach varying sizes, from small breeds like the Common Goldfish (up to 14 inches) to larger varieties like the Comet Goldfish (up to 12 inches) or the fancy Fantail Goldfish (up to 8 inches).

To prevent overcrowding, allow for at least 10 gallons of water per adult goldfish. This provides enough space for proper growth and minimizes stress and health issues associated with cramped living conditions.

In a 60-gallon tank, you can comfortably house up to 6 goldfish, striking a balance between providing enough space and keeping your tank visually appealing.

Factors to Consider

While the number of goldfish is crucial, it’s also essential to consider other factors that can affect your fish’s well-being and the tank’s overall health.

Tank Filtration

Adequate filtration is essential for maintaining water quality in your goldfish tank. Goldfish are notorious for producing waste, and a good quality filter will help remove toxins and keep the water clean.

Ensure your filter is suitable for a 60-gallon tank and has a high enough flow rate to handle the waste load.

Tank Decorations

Goldfish are curious creatures and enjoy exploring their surroundings.

Adding decorations to your tank, such as rocks, plants, and caves, not only provides entertainment for your goldfish but also helps create hiding spots and break up open spaces. Be mindful not to overcrowd the tank with decorations, as this can limit swimming space.

Water Parameters and Maintenance

Goldfish prefer cooler water temperatures between 65-72°F (18-22°C) and require regular monitoring of water parameters, such as ammonia, nitrite, nitrate, and pH levels.

Testing the water weekly and performing regular water changes are necessary to ensure a healthy environment for your goldfish.


In summary, a 60-gallon tank is an excellent option for goldfish enthusiasts. With a recommended maximum of 6 goldfish in this tank size, you can provide enough swimming space while maintaining a visually appealing aquatic environment.

Remember to consider factors like the adult size of your goldfish, tank filtration, decorations, and regular maintenance to ensure the well-being of your aquatic pets. Happy goldfish keeping!
