After the fish dies, it needs to be fished out in time. You can throw it away directly, or you can find a place to bury it, or you can feed it to cats and dogs. It should be noted that it is better not to cremate the remains of fish, on the one hand, it is not convenient to deal with, but also may be dangerous, on the other hand, it will pollute the environment.
1. Fishing out in time: The first thing to do for the dead fish is to fish it out in time. If it is not treated, it will slowly rot in the water, which may also lead to water pollution, thereby affecting the survival of other fish. After that, we should check the cause of death of the fish to see if it is the life span, or because of disease and other causes of death.
2. Check the water quality: There are many reasons for the death of fish, but it is usually the water problem. Therefore, it is necessary to check the water quality in time. If there is no timely remedy, it is very likely that the water quality will continue to deteriorate. You can use special testing equipment to check the Ph, hardness and temperature of the water to see if there is any change. If so, we should pay attention to adjustment.
3. Pay attention to turning over the tank: If the fish does not die normally and no other causes can be found, it is necessary to turn over the tank again, otherwise other fish raised in the future may also die. Drain the water and take out all the equipment in the tank. Re-disinfect and rinse, and fill with trapped water.
