History of Clean Your Aquarium Day
The Sumerians were the earliest documented aquarists and were known to keep fish in artificial ponds 4,500 years ago. However, it wasn’t until 1,000 B.C. that people in China started breeding and raising carp in large ponds for food. Later, in Japan, selective breeding of ornamental goldfish took place, and the breeding of ornamental carp was also perfected there. Similarly, the ancient Romans kept fish for food and entertainment; they also constructed ponds that contained fresh seawater from the ocean.
In the mid-1700s, people in England kept goldfishes in glass vessels. Still, the practice of keeping aquariums did not become popular until people became aware of the relationship between oxygen, plants, and animals.
Before the 19th century, the word ‘aquarium’ was used in botany to describe a container used to grow aquatic plants. The first display aquarium opened to the public in 1853 at Regent’s Park in London, followed by aquariums in Berlin, Naples, and Paris. Later, P.T. Barnum, a circus entrepreneur, opened the first display aquarium at the American Museum in New York City, and by 1928, the world had 45 public or commercial aquariums. Similarly, the first oceanarium opened in 1938 in Marineland, featuring a community fish tank and trained dolphins.
