Freshwater aquariums
Freshwater aquariums have been around for centuries and continue to evolve and improve. The first ever aquariums were nothing more than marble tubs filled with water and carp-like fish. Other early fish tanks were made from porcelain and resembled modern fish bowls. Around 50 A.D. the Romans began using glass on one side of their aquaria.
Thousands of years later glass is still the most common material used to build freshwater aquariums. Acrylic is gaining in popularity because it does not break as easily as glass. It is softer so it’s more susceptible to scratching. Manufacturers can solve this problem by adding a scratch-resistant outer layer to acrylic tanks.
Choosing between freshwater aquariums usually starts with picking a size. Most people want the largest tank they can afford, which is great fun but not always the best idea. A large aquarium in a small space can be distracting and most likely it will look silly. Larger aquaria are easier to maintain in some ways but they are more expensive to keep up.
