There are generally four reasons for the old death of raising fish at home. If it is due to poor water quality, it is necessary to change the water once a week, and the water volume shall not exceed one third. If it is because of too much feeding, it is necessary to reduce the feeding amount and choose the appropriate feed. If it is due to infection, you need to change water, heat up and add salt, or take a medicine bath. If it is because of mixed breeding of unsuitable fish, it is necessary to isolate the aggressive fish. 1、 If the water quality is not good, raise water first. Whether the water is good or not is very important for fish. Poor water quality can easily lead to fish death. Therefore, when opening the cylinder, it should be noted that both the water used for opening the cylinder and the water changed at ordinary times can only be used after drying for several days. In addition, pay attention to the frequency and dosage of daily water change. Not changing water frequently will also lead to the decline of water quality, and too often will stimulate the fish. Generally, change it once a week, about one-fifth each time, and no more than one-third. 2、 Feed too much. For many fish, they don't have the concept of full. As long as you feed, they will eat. In this way, it's easy to feed too much. If you feed too much, even if the fish doesn't die, it will suffer from gastrointestinal diseases and affect its health. Therefore, we must control the amount of feeding at ordinary times, and choose the appropriate feed according to the type and size of fish. 3、 Fish infected with diseases will die if they don't pay attention to treatment after they get sick. Therefore, we should pay attention to observe whether the fish have loss of appetite or don't like swimming. In such cases, we need to change water, heat up and add salt, and in serious cases, we need a medicine bath. In addition, generally, fish don't get sick frequently. If they always get sick, there may be a problem with the fish tank and they don't open it well when opening it. In this case, drug treatment alone is not enough, and the cylinder needs to be reopened for disinfection. 4、 Mixed culture problem many people like mixed culture. Many different kinds of fish are really good-looking when they are raised together, but it also depends on whether they are suitable. Some fierce fish or fish with cheap mouth will have trouble when they are mixed culture, and don't mix fish with too many body shape differences, otherwise there will be big fish eating small fish.
