There are basically two types of aquarium tanks: glass and acrylic. Although glass is still the most popular, acrylic weighs much less and is designed in a wide variety of shapes and sizes, making it aesthetically appealing. Glass tanks expand easily when filled with water and resist scratching, which provides great viewing. Acrylic tanks create some visual distortion because of the bending of the material when manufactured. Many hobbyists choose the more appealing, creatively-shaped acrylic tanks for this reason.
Here are a few examples of acrylic tanks that come in a variety of shapes and sizes:


A helpful tip – your Betta tank should be no less than 10 gallons! Anything smaller is simply not adequate because it reduces water stability within the tank and it won’t be big enough to house more fish along with your betta. It’s possible to purchase a smaller tank (3-5 gallons) if you plan on housing only a single betta. If you are serious about creating a wonderful environment for your fish and you intend to pursue the hobby of fish keeping, it’s a worthwhile investment to purchase a large tank to house your bettas.
