1. Space for your fish tank - How much room do you have for a fish tank. Buying a big fish tank for a small space may take away from the enjoyment if you are always bumping into it. Fish tanks can add to the natural beauty of a room when they are allowed to blend into it. You want to know how much space you have before you start to shop.



2. Shape of your fish tank - Consider the shape of the tank. Taller hexagonal and octagonal tanks are very popular, but it is a personal choice. Just like buying anything thing else, think about what appeals to you. Longer rectangular tanks are the most common type of tank and appeal to people who are doing this as a hobby.

3. Size of your fish tank - If you are new to fish and fish tanks it is advisable to start with a smaller tank. You will spend less and it will give you less work to keep it up. Small tanks hold anything from 10 to 20 gallons and cost you $10-$40 depending on the shape and size. If you find that you love fish and do not mind the upkeep you can always move up to a larger tank at a later date.

4. Where to Purchase - Where do you buy one? Of course pet stores and retail stores are the logical place. Flea markets, garage sales, eBay, and Craig's List offer good deals as well. Using the internet for research will give you some quick ideas on cost and style. Specialist websites can offer a wide assortment of aquariums to choose from.

Other things to think about include:

- Buy the fish after your aquarium is set up and the water is at room temperature.

- Keep the water at a warm temperature. Most fish do well at 76-79 degrees.

- Add some colored gravel to help hold the tank and plants down. Darker colors tend to bring out the colors of your fish better.

- Water weighs 9 pounds per gallon so be sure and get a fish tank that is sturdy enough.

- Keep your tank clean or get a quality filtration system. Algae build up can be a problem and you want to spend the time necessary to keep you tank clean and fish safe.

There are lots of things to think about when you are deciding which fish tank to choose. If you do it right from the beginning having fish will be a relaxing and enjoyable hobby.
