Extracted from the Wikipedia article Aquarium.
An aquarist owns fish or maintains an aquarium, typically constructed of glass or high-strength acrylic. Aquaria with flat walls are known as fish tanks or simply tanks, while those with rounded walls are known as fish bowls. Size can range from a small glass bowl, a few liters in volume, to immense public aquaria of thousands of liters. Specialized equipment maintains appropriate water quality and other characteristics suitable for the aquarium's residents.
