Aquariums, commonly known as watercourses, circulate water in an aquarium-like manner. Aquariums are commonly seen in saltwater and freshwater forms and can be thiet ke ho nuoi ca rong made from any solid or semi-solid material. An aquarium is usually a vivarium with at least one clear side where live aquatic animals or plants are housed and shown.
Fish and other aquatic animals can be kept in aquariums for many reasons, but the most popular reason for keeping aquariums is to provide an environment where fish are able to grow to their full adult size, including spawning potential. Some aquariums are even used for breeding purposes. Fish kept in aquariums will reproduce faster than those in public aquariums because the fish have the ability to heal when stressed. Fish kept in aquariums also have a much larger immune system than fish kept in smaller fish tanks or public aquariums.
Aquariums can be made of a variety of materials including metal, wood, plastic, fibre glass, quartz, or acrylic. Acrylic aquariums are the most popular and are available in a wide array of colours and types. Because acrylic is practically impenetrable by most fish, it is the material of choice for aquariums. However, because of the efficiency of the material it does not need to be as thick as glass and therefore the tanks of acrylic fish tanks are generally lighter than fish tanks which use glass.
There are two basic kinds of aquariums, the warm water tank and the cool water tank. A warm water tank is one in which the fish are kept in a closed system of water in order to keep the temperatures stable. The fish do not come into contact with any of the outside world and there is no risk of sudden changes in water temperature due to external influences. The warm water aquarium uses electricity to heat the water and this process is very effective if used for a long period of time. The only drawback of the warm water aquarium is that the fish tend to be happier in a warmer water temperature. On the other hand, a cooler aquarium will require that the water temperature is maintained at a constant temperature so that the fish do not become stressed.
Cooling is more efficient than heating and this means that the fish tanks can be kept in a wide range of temperatures. Aquarium enthusiasts who keep fish often choose to use a combination of both types of aquarium to ensure that their fish are kept in perfect conditions. If the water is heated, the fish need to be kept in an enclosed system of water. Therefore, a combination of a heater and an air conditioner is required along with a cooling unit, which is specially designed to keep the water at a constant temperature.
There are many different accessories available for fish tanks. Tank filters, pumps, power heads and thermostats are available as accessories. The aquarium filters help to maintain cleanliness by removing fish waste products from the water. The pump helps to push water through the aquarium and the thermostat controls the temperature of the water. The various types of thermostats included in the various tanks ensure that the aquarium remains at a consistent temperature.
