An aquarium is a water-filled tank in which fish swim about. Most modern aquaria are made from glass, acrylic, or fiberglass. They come in a variety of shapes and sizes, with the most common being the rectangular aquarium. There are also hexagonal, bowfront, and corner tanks. Aquariums can be small enough to fit on a desk or large enough to walk into. The largest aquarium in the world is located in Atlanta, Georgia and holds over 10 million gallons of water!
The term Euro style aquarium generally refers to an aquarium that has been designed and built using European standards. This typically means that the tank is constructed of high-quality materials, such as glass or acrylic, and features clean lines and minimalistic design elements. Euro style aquaria are often used for freshwater fishkeeping, although they can also be adapted for saltwater use. Many people believe that Euro style tanks provide a more naturalistic environment for fish, as they closely resemble their wild habitats.
