People have been collecting fish in containers for thousands of years. At least 4,500 years ago, the ancient Sumerians kept fish in artificial ponds. One of the premier cultures to successfully breed fish was the Chinese, who later passed their knowledge on to the Japanese. Fishkeeping didn’t become an established hobby until the 1800s, when the relationship between oxygen, animals, and plants became better known.
The all-glass aquarium that many people now use became available in the 1960s. Popular aquarium fish for those new to the hobby are angelfish, tetras, guppies, mollies, and platies. A primary requirement for keeping aquarium fish healthy is good water quality. Water must be free of pollutants and changed often.
Featured on the strip of four “Aquarium Fish” stamps are 23 species of fish, coral, sponges, and other specimens that populate reefs in different parts of the world. The stamps were based on more than 20 photos, as well as advice from aquarium experts.
Home aquariums are either freshwater or saltwater tanks. Freshwater tanks are easier to maintain, but saltwater fish create a more colorful display. Some aquarium residents scavenge for food, others control algae growth, or provide oxygen through photosynthesis.
