Fish Aquariums Give your fish a home you'll both love. We can help you find the right solution for your fish and your space. Maybe you have a goldfish or two, or your collection runs into the exotic. Or you may be looking for one-gallon tanks or 150-gallon fish aquariums (or something in between). Many of our aquariums are made from glass or acrylic. Glass is often the top choice for high-quality fish tanks. Acrylic fish tanks have some advantages and disadvantages. Acrylic aquariums are much lighter, durable and less prone to leaks, and manufacturers can bend and shape tanks into many different forms, such as corner units, bow front tanks, globes, hexagons and even creatively designed betta tanks! If you live in an earthquake prone area, acrylic tanks might be the safest choice. However, glass tanks don't scratch as easily, are less porous and don't become discolored over time. Older acrylic tanks are more prone to yellowing, but newer acrylic models are much less likely to discolor. The good news is that whatever you choose, we have a wide variety of both acrylic and glass fish tanks at PetSmart! Most home aquariums are rectangular, but there are other shapes as well. Rounded globe tanks mimic the look of the classic fish bowl while still performing proper filtration, aeration and cycling of the water. Aquarium cubes can fit almost any space, while corner fish tanks will fit conveniently in any room. Hexagon tanks are perfect for office desks or any area that is taller than it is wide. You'll find matching aquarium stands for every shape!
