What about the aquarium? Everyone knows that an aquarium is a vivarium that is usually placed in place with a transparent side (glass or high-strength plastic), where animals and aquatic plants (usually fish, but also can be found invertebrates, amphibians, marine mammals, and reptiles) in public. The aquarium comes from aqua latin which means "water", and the suffix -critical means "place associated with". So it can be concluded the aquarium is a place to store fish.
