Fish culture at home must be fed at regular intervals. Fish farming seems to be a leisure thing, but if you want to raise it well, you must pay attention to feeding it. Usually, it should be fed two or three times a day, and each time it should be fed regularly and quantitatively, so that fish have good eating habits and are not easy to get enteritis. In addition, the feeding amount should not be too large to avoid bad water.

Because the water used for fish farming at home is limited, with the help of filtration several times, the water quality will deteriorate and the ammonia nitrogen content will increase after a long time, so it is necessary to change water to improve the water environment. Usually, it should be changed every seven days. If it is filtered well, it can be changed every fifteen days. Each time, the water is changed about one quarter of the total water volume.

If tropical fish are raised, water temperature is also an important influencing factor. Usually, the temperature should be kept above 20 ℃, and for some fish, it is best to keep above 24 ℃. In the fish tank, it is necessary to control the temperature with a heating rod, so as to keep the temperature constant and not change too much.

Fish farming should also pay attention to disease prevention. Once the common diseases such as white spot disease and water mold are infected, the fish will die. In addition to paying attention to changing water and controlling temperature at ordinary times, anything entering the fish tank should be disinfected to prevent them from bringing harmful bacteria and parasites into the fish tank and causing fish to get sick.
