People in the course of history have developed many interests and tastes for certain elements in particular. Among one of those tastes or hobbies for something in particular appears the aquarium, just as its name implies is the taste or liking for fish breeding in aquariums, where to some extent control aspects of life the even, but we must bear in mind that not only fish but any type of body that can live in water and can be controlled easily by humans. This hobby called aquarium, although it may be a little bit strange and yet for some people eat in the world, is a practice that takes place long ago in history, so much so that there are data going back to 2000 years ago when goldfish were used in containers or ponds for the purpose of beautifying a place, which is a clear example of the aquarium when using containers that would be the goldfish aquariums and ornamental purposes. Entering more on the historical development of the aquarium, it is worth highlighting the fact that from ancient China is done raising goldfish, in what appeared to be a ceramic deposits, but these days the control to the life and environment of the fish was very basic, not to say that at least they do not there were any systems that provide extra support to fish in such a hobble in those days used for aquarium fish species were very resistant, it should support issues such as the constant water changes because they had no means to maintain control cleaning the water in which fish were. This type of basic systems, in addition to archaic remained for long in history, until today, with the use of tanks, no clutch and you begin to notice the change with the development of modern aquariums or elements that keep track of aquarium water. The aquarium is now a hobby that has achieved high levels of knowledge and implementation of high-tech devices, which means a great sophistication, so much so that and can be considered a hobby but not a science, which knows about the topic is called aquariology. In the past the aquarium was not a hobby that had great boost to their training, they were not made available to the elements that allow optimal control of fish life, since it would not be offered more support to change the water keep the environment of fish is inadequate for their life and regularly gave them food for their livelihood, but now, there is a major intervention in the tank, because what is done with these is to try to completely recreate the environments in which the fish would live normally, which is an excellent example of what the aquarium, so artificially recreated ecosystems.
