Fish make terrific pets, and finding the best fish tank helps ensure that they live long, healthy lives. Whether you already have fish and are contemplating an upgrade to your current tank or you’re a novice fish keeper looking for your first tank, there are a few things to keep in mind as you shop for the best fish tank for your home.
First, decide how many and what type of fish will live in the tank to help calculate the right size. Some fish need more space than others, while others live alone rather than in a school.
After determining the quantity and type of fish you want, you should have an idea as to the size of tank needed. Fish tank sizes are measured in gallons; some of the most common sizes for beginners and experienced fish owners are three, five, and 20 gallons.
Next, consider how much the tank will weigh once filled with water. Since most tanks are made of glass, the tank along with its water can be heavy. If you use a stand for your tank, consider whether it can handle that much weight. For example, a 20-gallon fish tank weighs about 225 pounds when filled with water.
