The first thing to do in fish farming is to change water.Because the water in the fish tank is limited, the water quality will age over time, although the water looks clear, but there are many harmful substances, which will increase the risk of fish illness, and may also affect their development.Therefore, it is necessary to change the water regularly, usually once a week, to maintain a good water quality, or half a month for a change, each time for about a quarter.
Fish farming needs to feed it, usually using artificial feed, which is balanced in nutrition and very helpful to the development of fish.It should be noted that although the fish has strong hunger tolerance, it can not be fed once every long time, it must be fed frequently, two to three times a day, but the amount of feeding should not be too large each time, which is conducive to its growth, but also not easy to spoil water.
Many common ornamental fish are tropical fish, such as guppy, swallow fish, arowana, etc. When raising them, attention must be paid to controlling the water temperature. If the temperature is too low, it will affect their feeding, and even lead to their death.Usually the water temperature should be kept between 20-30 degrees Celsius, although some fish can withstand low temperatures, but it is best not to be lower than 18 degrees Celsius.
The fish tank must be cleaned regularly, usually once a month.Cleaning the fish tank is mainly to discharge the dirt in the tank and remove the scale and algae on the tank wall.Before cleaning, the fish must be fished out, and the trapped new water should be prepared, so that the fish can continue to be raised after cleaning.
