The cold water aquariums are very common among people, and especially stand out because they are often the first to purchase most people when they want to have fish as pets. At first it is always advisable to bow by the cold water aquariums of about 20 liters, bearing in mind that we can place a fish every 2.5 liters of water and must complement the tank with a filter and an oxygenator, which can be achieved in any pet store or in a skilled trade.

And if possible, we also need a lid having a fluorescent tube, that is very necessary because with the lid not only avoid the evaporation of water, but also will prevent fish from jumping out. Another of the most important for the maintenance of cold water aquarium is a thermometer, because many times, due to air conditioners that we use in summer and heating in winter, can cause water to become excessively something hot or cold, which can affect the life of the fish that inhabit the aquarium. On the other hand, the cold water with which these tanks are filled usually tap, and as we know, despite being water, it contains residual chlorine and some metals. To avoid affecting the fish we can add the water a kind of salt that usually sell pet stores. It is important for us anyway ADVISE correctly.
