About the Aquarium

An aquarium is the keeping and cultivation of ornamental fish (goldfish, killifish, etc.) and aquatic plants in an aquarium. Different people have different ways of focusing on it and different things they want. In this article, we would like to explain such an aquarium.

What is an aquarium?

An aquarium is the breeding and cultivation of ornamental fish (goldfish, killifish, etc.) and aquatic plants in an aquarium.It is often used in a broad sense, from personal hobbies to exhibits in aquariums. It also encompasses a wide range of scale, from small tanks to large aquariums (fish tanks). The number of hobbyists has been increasing in recent years because of the individuality of the fish kept in aquariums, which include ornamental fish such as goldfish and killifish, as well as tropical fish.

History

In the history of aquariums, over 2,000 years ago, selective breeding of crucian carp began in China and goldfish were born. From that time on, the aspect of appreciation, rather than as food, emerged. A thousand years later, during the Song Dynasty, goldfish were brought indoors to be kept in ceramic containers and enjoyed. Later, goldfish gradually became a popular hobby with the appearance of the splendid aquarium with a cast-iron framework that was exhibited at the World's Fair in London in 1851. In Japan, it became fashionable around the 1970s to keep tropical fish in an environment similar to their natural habitat, and in the 1980s, more and more tropical fish began to appear as part of interior designs in TV dramas, etc. The expansion of fish keeping equipment and the suppliers of such equipment led to an increase in the number of aquarium enthusiasts. During the bubble era, aquariums containing tropical fish were placed near the front desks of hotels and in the living rooms of wealthy people. In the 2000s, the number of people keeping small tropical fish and aquatic plants increased in tandem with the spread of the Internet. However, the number of people who manage their own aquariums increased compared to previous years. And one of the reasons for the increase in the number of individuals is that information about what they don't know and what has gone well is now readily available thanks to the Internet. And in recent years, after social networking sites such as "Instagram" and "Twitter" became popular, aquariums have come back into the spotlight from the viewpoint of looking good and impunctuating, and the number of beautiful varieties of killifish and other living creatures has also increased with the increase in the number of species of killifish. The number of aquariums using killifish is on the rise.

How to do the waterweed school

There are two types of aquarium owners: those who focus mainly on aquatic plants (aquarists) and those who focus mainly on living organisms (biologists).And if those who are going to do aquariums do not first consider what will be their main focus before doing so, they will likely regret it later.First of all, in the case of an aquaculture group, the beauty and balance of the water plants is the key to success, so it is necessary to accelerate the growth of the water plants in order to make them look beautiful. Then, when the plants have grown to a certain degree, the old and dirty leaves are disposed of. To stimulate the growth of the water plants, sunlight (even LEDs) and carbon dioxide are needed.This is because water plants are plants and grow through photosynthesis, and light and carbon dioxide are essential for photosynthesis. Therefore, those who mainly work with aquatic plants inject carbon dioxide into the water to increase the concentration of carbon dioxide in the water. At this point in the explanation, you may have noticed thatHigh carbon dioxide levels in the water increase the risk of organisms dying from lack of oxygen for their survival. Therefore, the water plants group tries to reduce the number of living organisms as much as possible.Also, water quality deteriorates at a faster rate with living organisms in the water, so water changes are necessary, but the risk of removing water plants that have finally taken root if the water is changed is another reason for not allowing many living organisms in the water.

The biological school's way

In the case of the biological group, this refers to competing with organisms, such as ornamental fish, the next time they are added. Generally speaking, the number of people who are in the organism group is larger than the number of people who are not. It is more enjoyable to keep mainly living organisms, especially if you are not an outstanding aquarium hobbyist. As explained above, it is more difficult to keep living organisms if you focus mainly on aquatic plants. On the contrary,When you focus mainly on living organisms, you may neglect the aquatic plants. This is because it is difficult to use carbon dioxide, which promotes the growth of aquatic plants, when you use mainly living organisms. In addition, it is even more difficult to keep the aquarium clean because the organisms in the aquarium may eat the plants. If you use organisms as the main source of carbon dioxide, you need to increase the oxygen concentration in the water, not carbon dioxide.When oxygen levels are low, there is a risk of oxygen deprivation. To prevent this from happening, you can take measures such as adding air and using plants such as aquatic plants to make oxygen. For these reasons, we recommend that you think carefully about what you want to do as your main focus before doing an aquarium.
