Aquariums big or small are available in either glass or acrylic. Each is a fine product which has pros and cons such as the glass aquarium when in smaller sizes is generally much more affordable than acrylic. Acrylic aquariums are actually stronger than glass as the material is chemically bonded together instead of being held together with silicone like glass. One factor to keep in mind about acrylic aquariums is that since it is a softer material than glass it is more prone to scratching. The good news is those scratches can be repaired.
