Fact #1. Archaeological evidence of fish-keeping dates back to the times of the ancient Sumerians and Egyptians. They considered fish to be sacred creatures. The Chinese also kept goldfish and bred them selectively during the time of the Sung Dynasty. These fish were kept for purely decorative purposes. People were forbidden to eat them.
Fact #2. The process of maintaining the water for a fish tank was not well understood until the time of an English chemist. He's credited with studying the tank's requirements to have its water cycled in order to keep fish alive for extended periods of time. By studying a 13-gallon container full of goldfish, eel grass, and snails, he succeeded in creating one of the first stable tank ecosystems.
Fact #3. During the Victorian Era, a common design for the home aquarium was a glass front with wooden sides made watertight with a pitch coating. The bottoms of many of these tanks were constructed from slate and heated from underneath. By the 19th century, the tank evolved to include glass with metal framing.
Fact #4. One must realize that an aquarium is a living, breathing, contained, and miniaturized ecosystem with many variables to consider. This is regardless of the type of tank you choose. These variables need to be properly balanced in order to work together and allow one's fish to flourish. That said, if you're new to fish-keeping, start slowly. Invest in a small glass freshwater or coldwater tank.
Fact #5. Consider the size, shape, and materials of the fish tank you want. Do be aware that glass is fragile and heavy. You must be certain you'll have room to transport a glass tank and ample space to place it. Some tanks are octagonal in shape, which can be ideal for placement in corners.
