As a general rule, purchase the largest size tank you can afford. A larger aquarium is easier to maintain and better for your fish. You’ll also save money in the long run because you won’t have to buy a larger tank when your fish grow or when you want to add more fish or décor.
To make sure your fish have room to swim and grow without feeling crowded, follow the guideline of one inch of fish to one gallon of water. This is a good rule for all fish except goldfish. Goldfish require a little more room to move around than other fish, so use the rule of one inch of fish to two gallons of water.
Don’t forget to consider purchasing an aquarium stand made to fit the size of the tank you are going to buy. A complete aquarium including water, gravel and fish weighs about 10 to 11 pounds per gallon. Aquarium stands are specifically designed to hold this much weight, but a sturdy piece of furniture or counter will work, too.
