Aquariums are self-contained biological systems designed to contain water and appropriate nutrients for the growth of aquatic organisms. An aquarium is generally a semi-open system with at least one visible side for the inhabitants to swim around. Fish keepers typically use aquariums to maintain aquatic animals, amphibians, marine reptiles, and sometimes even live plants. Aquariums are commonly referred to as glass houses or tanks, due to their transparent glass “tops”, but the term can also apply to the plastic “containers” used to contain freshwater fish or saltwater aquarium plants. Aquariums are widely used in homes, schools, and public aquariums all over the world.
The popularity of aquariums has soared in recent years as more people have discovered that these beautiful creatures provide a unique environment that is both soothing to the senses . Many public aquariums, as well as small private aquariums, have experienced an increase in popularity since the early 1980s when the first wide-ranging aquarium was installed at the Museum of Modern Art in New York City. Aquariums can be found in nearly every major city in the U.S. and elsewhere in the world thiet ke ho ca canh . Aquariums now account for a large percentage of the living aquarium market.
Widely used types of aquariums are the aquariums that are constructed from a variety of plastics materials such as PVCu, polycarbonate, and acrylic. These are available in a wide range of colours and are available in a variety of shapes and sizes. Aquarium tanks that are constructed from PVCu are not only highly resistant to breaking, but they are available in such a wide selection of colours that it is easy to personalise the look and feel of your tank. Polycarbonate aquariums are also very popular and are constructed from a durable material that is not susceptible to cracking and will not degrade. Aquariums that are constructed from acrylic are also popular and are made in a wide range of colours and designs. Aquariums that are constructed from fibreglass are generally more expensive than PVCu or acrylic and may not be suitable for everyone’s tastes.
The second most common type of aquarium used today are the saltwater aquariums and the fish that inhabit them are chosen for their specific characteristics. For instance, a colourful fish with a vibrant colour tail might not be a good choice for a research aquarium. However, colourful fish are commonly chosen for the public aquarium as they make fascinating sights to watch and many aquarium keepers find that selecting the right fish can have significant impact on the way that their tank is visited by visitors. For example, certain fish species attract more visitors than others and keeping this information in mind, new aquarium owners may be better able to select fish with particular attributes that help increase the number of visitors. This research knowledge has had a significant impact on the selection of certain animals for the public aquarium.
Aquariums that are used for scientific research need to be highly controlled and this is particularly true for ocean tanks. Oceanic aquarists must make sure that the water chemistry is very stable and this can often be achieved by controlling the circulation of the tank. Controlling the temperature of the ocean water will also help ensure that it is a more stable habitat for marine animals.
It is important to remember that when choosing an aquarium for scientific purposes, the environment needs to provide the best conditions for the marine animals that will be kept inside. The aquarium would need to be designed so that the fish would get the food that they require and the tank also needs to be maintained in a way that is similar to the natural ocean environment. If these requirements are not met, the marine inhabitants could become stressed and possibly die. New owners of marine aquariums should bear this in mind before choosing an aquarium.
