I build aquariums for a living! I am a hobbyist as well and keep some aquariums at home! How about you?
I don't but I am fascinated by them.  What kind of fish are in your aquarium?
Awesome! I keep exotic fish, turtles, and aquatic plants in my tanks! I love feeding them at work.
That is so cool.  Is it hard to build auariums?
The aquarium principle was fully developed in 1850 by the chemist Robert Warington, who explained that plants added to water in a container would give off enough oxygen to support animals, so long as the numbers of animals did not grow too large. The aquarium craze was launched in early Victorian England by Gosse, who created and stocked the first public aquarium at the London Zoo in 1853, and published the first manual, "The Aquarium: An Unveiling of the Wonders of the Deep Sea" in 1854. An aquarium is a
water-filled tank in which fish swim about. Small aquariums are kept in the home by hobbyists. There are larger public aquariums in many cities. This kind of aquarium is a building with fish and other aquatic animals in large tanks. A large aquarium may have otters, turtles, dolphins, and other sea animals. Most aquarium tanks also have plants.
An aquarist owns fish or maintains an aquarium, typically constructed of glass or high-strength acrylic. Cuboid aquaria are also known as fish tanks or simply tanks
