Aquariums have been around since the earliest times, used for multiple functions by ancient civilizations all over the world. The first aquariums were probably constructed lam ho ca hai san out of wood because it was readily available and simple to make. In modern times, acrylic has replaced wood because of its greater strength and ease of fabrication. Aquariums can be found in all shapes and sizes, from extremely large multi-storey structures to individual tanks placed in homes and offices.
An aquarium is basically a vivarium with at least one flat side where live aquatic animals or plants are housed and displayed. Most fish aquariums are made in standard sizes so that no fish will find it difficult to move about, although larger aquariums are now being made. Most fish tanks (also known as fish tanks) are generally the same size, but some have specially made “splash” areas under the water that are useful for keeping small pets like guppies or tropical fish. Fish keepers also use aquariums to house other animals, invertebrates, aquatic reptiles, amphibians, and marine corals.
Tank size depends on the number of animals you want to keep in your aquarium. The average number of fish you usually see in an aquarium is between one and three, though this is not always the case. If you plan on keeping fish of various sizes, the amount of space available in the tank will affect the size of fish you will need to place in it. Larger marine animals (such as sharks, schools of fish, etc.) need much more space than the average aquarium.
There are two basic types of aquariums: vivariums and terrariums. Vivariums are self-contained, which means that the fish inside the tank interact with each other and can “see” through one another’s glass. This type of aquarium is very popular for families. On the other hand, terrariums are similar to fish tanks except that they contain additional items such as live rocks and coral for the fish to interact with.
If you plan on keeping an aquarium with plants, algae might be present. Algae can be a major problem in an aquarium since it can destroy the normal oxygen cycle in the tank. You will need to take care of this problem by using an aquarium aerator. An aquarium aerator will draw the water out of the tank and move it into the air where it can be recovered and used by the plants. Aquarium aerators also help remove toxic gasses from the water, which is beneficial if you have an ammonia-based aquarium freshwater fish.
Proper filtration and aeration are essential to healthy aquariums. They can be purchased separately, but many times aquariums are started together as a set. The best way to start an aquarium is with a well-established biological filter, such as a biological filter pad, or even a biological filter assembly. You may not always be able to use the biological filter all at once because it may not filter out all of the gasses and organic pollutants in the water. Aquarists usually combine carbon filters with an air pump to complete the aquarium setup. You should read about how water quality is tested for fish tanks before you purchase any products, or before you start a new aquarium.
