Fish farming must first raise water, usually household water is tap water, this water after factory treatment, will not contain dirt, but there will be chlorine residues in the disinfection process, which is still very dangerous for fish, so must go through water trapping treatment. Put the water in a sunny place to dry for a few days before it can be used to raise fish.
If you raise a wide range of temperature fish, such as goldfish or koi, they do not require high water temperature, as long as it is not too hot or too cold, can be raised alive. But some tropical fish situation is different, if the control of water temperature is not good, the temperature is too low will lead to its death, even if alive, appetite will decline, so need to be properly heated, can be maintained between 20-30 degrees Celsius.
Fish farming needs to change water, according to the deterioration of water quality, you can choose to change a few days or a few weeks. If the filter system in the water is better, it is no problem to change it once a month. Generally, the water can not be changed completely, most of the old water should be retained in the fish tank, and only one fifth or one quarter of the new water is enough.
Fish farming needs to feed feed regularly, usually 1-2 times a day, although feeding once a few days can not starve to death, but the fish is easy to grow. In addition, we must choose the right bait according to the feeding habits of the fish, if the feed is not acceptable, the fish may not eat, this time need to be replaced in time.
