Choosing The Goldfish Aquarium Tank
Goldfish need enough space and should have a well-equipped aquarium. The tank should contain at least 10 gallons of water per goldfish, even more if your fish are larger than average. It should also have enough water-surface to accommodate your fish - that is why a box-shaped tank is better than a fish bowl.
As a rule of thumb, goldfish shouldn't live in a bowl. While a large bowl may be suited for a small betta fish, it is usually too small for a goldfish. Goldfish need enough room to swim around. A single goldfish may grow to be up to 10 inches long, and goldfish like some company, so you should keep at least two of them together. A bowl is also difficult to clean and won't accommodate filters and other equipment.
You have to decide where to place your goldfish aquarium well before you set it up. Moving a full aquarium is not only difficult, it may actually crack the tank. Make sure that the goldfish aquarium is placed on a sturdy piece of furniture. When full of water, gravel, equipment, it is going to be quite heavy! If in doubt, buy a designated aquarium stand. The chosen location should be near an electrical outlet, but in a place where splashing water won't cause any harm.
Don't forget to place your goldfish aquarium where you and your guests can watch and admire your goldfish.
