Goldfish grow to the size of their tank, with some species easily reaching 8-10 inches. Goldfish are high-bioload fish which means they need an aquarium with a strong filtration system. A tank with an under-gravel filter provides some filtration, but it doesn’t do as good of a job as other options like hang-on back filters or canister filters. Goldfish bowls aren’t the best option because they don’t provide any filtration for your fish. Tanks allow you to control and regulate the amount of heat in the tank via equipment like heaters. Bowls don’t allow for the heat to be regulated as well as tanks do because there is no room for a heater. Goldfish require specific water temperatures to survive. Tanks provide more than bowls, which makes them a better option. Goldfish need a lot of oxygen, so you want to make sure there is enough surface area for your fish to breathe when they are in their natural habitat. Oxygen is able to enter and carbon dioxide can exit the tank through the surface of the water.

The surface area of the water is where gas exchange occurs. With more time and experience, hobbyists have come to realize there are multiple reasons to keep your goldfish in a full-sized tank versus a bowl. Goldfish Tanks versus Goldfish Bowlsįor decades, goldfish bowls were the standard containers for pet goldfish. Consider purchasing a used aquarium in good condition instead of buying cheaply made new tanks. Like most things, you get what you pay for. Make sure all components fit well together and look at reviews from previous customers. Cheap materials like poor-quality glass and plastic can break, warp, or scratch very easily. The quality of the tank is important because you want it to last for years. And the bigger the tank, the more expensive the tank itself and its corresponding equipment.

The bigger the fish, the bigger tank you will need. The size of the tank needs to reflect the size of your goldfish.

The aquarium itself will be a good chunk of your initial expense. Before you purchase a goldfish tank, have an idea of your target budget for all equipment, including filters, tanks, aquariums, cleaning supplies, etc. This should go without saying but the price of the tank is important. Glass and acrylic are both safe options but you should avoid plastic tanks because they scratch easily and aren’t as durable. The downside of acrylic is that it scratches easily and needs more precise cleaning care products. Acrylic is lighter weight – usually about half the weight of a glass aquarium – and more durable. There is obvious risks involved with glass, though, if it were to be dropped and break into individual sharp piecesĪcrylic fish tanks are often more expensive than glass. It’s easy to take care of and can be purchased in a range of thicknesses and styles. Glass is the most commonly used material for fish tanks.
