When it comes to selecting the best tank for your goldfish, size is key. Goldfish are messy fish that need lots of space to swim and dilute out their waste. Even if you have a large system, the key is to keep your bioload low so your fish stay healthy and your maintenance routine minimal.

“Goldfish tanks are frequently overstocked when they are new, leading to New Tank Syndrome,” Dr. Jessica Koppien-Fox, DVM and CertAqV—a certification for experts in aquatic veterinary medicine—told The Spruce Pets. “Owners can avoid this by only adding a few fish at a time or having a very large system. When setting up any tank, all fish require aeration and filtration to keep their tanks healthy.”

Don’t put your goldfish in an antiquated bowl. Despite the long association between goldfish and bowls, fish bowls are not proper homes for any fish. It is inhumane and cruel to keep your fish in a standing cup of water with no filtration.

If this is your first aquarium, check out our list of everything you’ll need to keep your fish happy including a robust filter, décor, substrate, and more.

We also recommend against the small, 10-gallon aquariums commonly marketed at pet stores and big box retailers. These tanks are too small for an adult goldfish, let alone multiple goldfish. Instead, your tank should provide approximately 20 gallons of water per fish. Goldfish can also grow to be quite large, and fully grown goldfish should have 50 gallons of space.

Our favorite goldfish tank is the Tetra Glass Aquarium 55 Gallon Rectangular Fish Tank, which allows for custom filtration tailored to your goldfish. For example, comet goldfish require a lot of filtration, while some species of fancy goldfish with specific swimming difficulties may need a carefully directed flow of water so they do not get pushed around the tank. We also have several other tanks we love that may work better for your specific setup.

Here are the best goldfish tanks.

What to Look For in Goldfish Tanks

Tank Volume

When it comes to goldfish, the more water, the better. Goldfish have low feed-to-mass conversion, meaning that they eat a lot and don’t put on much mass. This means that there is a lot of food wasted in your tank. This can cause lots of issues with your water chemistry, so the larger volume of water to dilute everything out, the easier maintenance will be. Goldfish can grow up to 12 inches long, so although they may start small, plan for your fish to get a lot bigger!


Narrow aquariums may fit your home, but they are not the best choice for goldfish. Being larger fish, you want to make sure your fish can turn around easily whenever they like. If they are forced to turn in tight spaces, you may see spinal disorders. If caught early and moved to a larger system, these can be corrected.

Fancy goldfish in particular are prone to buoyancy disorders. This can be aggravated by a lot of water pressure on top of them from a very deep tank. For fancy goldfish, a tank depth of 18 inches or less is best to manage their buoyancy.


Aquarium tanks come in two materials: glass or acrylic. Glass is more traditional, but can be delicate and heavy. Acrylic is lighter and more durable, but often not as clear as a glass tank. How you clean your aquarium depends significantly on what type of material is present in your tank.

Never use glass cleaning supplies on acrylic since it will scratch the material. This includes any metal algae scrapers.

Additional Equipment

Although these recommendations focus on tanks, there are lots of other components you will need for your goldfish tank. A strong filter is a must, unless you have lots of fancy goldfish that are blown around by a strong current. Goldfish will need a substrate and décor items to complete their tank setup. Goldfish are temperate fishes, so you won’t need a heater unless your home gets very cold.

  • How big of a tank does a goldfish need?

    Goldfish need a lot more room than you may have been led to believe. These fish are messy and grow very large and will therefore need at least 20 gallons PER FISH just to start. As they grow bigger, you may need 50 or even 100 gallons for large comet goldfish.

  • Can goldfish be in a tank with other fish?

    The biggest consideration in choosing fish to be in a goldfish tank is their temperate nature. This means the like nontropical temperatures around 65-75 F. Good choices for goldfish companions includes other goldfish, zebrafish, or minnows. Try not to mix long-bodied goldfish, such as comets and shubunkins, with fancy varieties, such as orandas, ranchus, or black moors. Long-bodied goldfish easily outswim and outmaneuver fancy varieties, hogging the swimming space and the food.

  • Can I keep my goldfish in a bowl?

    Absolutely not. Bowls are not a humane choice for any fish. All fish deserve filtered, flowing water.
