Tips in Selecting an Aquarium Tank
Although some fish species require larger tanks, there is a rule of thumb for determining appropriate tank size. For fish with an adult size of less than 4 inches, like tetras and guppies, allow one gallon of water for every inch of fish. For larger fish, water requirements can vary greatly between species, so do your research. A large cichlid requires a 55 gallon aquarium, and an angel fish needs 29 or more gallons, even though the adult sizes of these fish will never approach 55 or 29 inches.
Aquarium tanks come in many sizes, anywhere from two and a half gallons to several hundred gallons. They may be rectangular, bow-front, or hexagonal, or designed for a corner, among other shapes. Smaller tanks are a good choice for a first aquarium, because they generally have lower maintenance needs. Don’t go too small, though, or your fish won’t have enough room. For a first aquarium, consider a prepackaged kit containing everything you need to get started, like a filter, light, and heater.
Aquarium tanks can be found in both glass and acrylic styles. Those that are glass are less expensive and widely available. The glass will not scratch, but it is heavy. Glass aquariums come in limited shapes. Compared to glass, acrylic is lightweight. The acrylic material allows for a wider range of custom shapes and sizes. They are easier to scratch than glass aquariums, however, and are usually the more expensive option.
An aquarium weighs about 10 pounds for every gallon of water once it’s filled. A large aquarium can be very heavy. Choose a stand that can support this weight; don’t just place your large aquarium on a table or bookcase, because it could collapse under the weight. Specialized aquarium stands in metal or wood provide aquarium supply storage and an attractive, sturdy method for holding the tank. Besides the aquarium and a stand, you’ll also need a lid for the tank. Sometimes this is referred to as a ‘hood.’ This is often purchased as a set with the aquarium itself so that you can be sure it is the appropriate size.
Once you purchase your aquarium tank, place it in your bathtub or backyard and fill it with water. Add your heater, filter, and any other equipment, and plug these items in. Then, wait overnight, to test both the aquarium tank and the equipment. You don’t want to add fish immediately only to find out that the tank leaks or your heater does not work. Selecting the proper aquarium tank size and type, and making sure that it is ready for fish before adding them, can ensure that your fish will live a long and happy life in your aquarium.
