Aquarium
Aquariums are man-made habitats that contain a variety of fish, plants, corals, or other aquatic organisms.
Two main categories are freshwater aquariums and saltwater aquariums, which often mimic the marine environment.
The more artistic types of aquariums use natural elements to create an aquatic landscape. In the absence of artificial decorations, these natural aquariums take our environment as their source of inspiration. Whether it’s an underwater Amazon jungle, Japanese “Iwagumi” rock formations, or a tropical coral reef, having a living work of art in your home has never been easier or more exciting!
