regularly. Only when the water is good can the fish be good. Usually there is a filter in the fish tank, but even so, the water should be changed regularly, because the water quality will age and affect the health of the fish. According to the maintenance of the water body, decide the cycle of water change, if the water is easy to go bad, it is necessary to change the water once a few days, if the water quality is maintained well, it is also possible to change it once a week or two.
in order to ensure the healthy growth of fish, we should also pay attention to feeding at ordinary times. Feeding is usually two or three times a day, preferably spaced out, but after 9 am and before 4 pm. It is better to feed regularly and quantitatively each time, which is more conducive to the absorption and growth of fish, and it is better to ensure that fish can eat within 5-10 minutes.
If you raise tropical fish, you must control the water temperature, usually above 20 degrees Celsius, so that the fish can grow healthily. If the temperature is low, the fish's appetite will be affected and become very inactive. In addition, even for some eurythermic fish, the higher temperature environment is also conducive to their growth and development.
Fish also need a certain amount of oxygen to live in the water. If the dissolved oxygen in the water is insufficient, the fish will not be able to breathe, which will lead to their death. In view of this situation, the best way is to use oxygen pump to oxygenate, 24 hours to ensure the supply of oxygen, so as to cut off the possibility of fish hypoxia.
