The fish in the tank refers to the first batch of fish put into the tank after the new tank is filled with water. The reason why we need to break through the tank is that it is not easy to judge the quality of the water body, and it is more reliable to use fish directly to experiment. As long as the fish can survive in the new tank for a period of time, it means that the water is well raised and the tank is successful. If you fail to break through the tank, then you have to re-open the tank to raise water, and then continue to try.
1. Fish fishing: The fish that failed in the tank must be fished out in time, so that the remaining healthy fish can continue to live in the tank. Because it is not sure whether it is a fish problem, so do not rush to re-open the tank, but the fish still have to be fished out, whether sick or dead, may affect the water quality, is not conducive to the survival of other fish.
2. Water change: After the fish that failed to break through the tank is fished out, the next thing to do is to change the water. No matter whether there is any problem with the water, it is good to improve the water quality by changing the water. And sick or dead fish will also leave some harmful bacteria and other substances, water can remove some, thereby reducing the possibility of other fish illness or death.
3. Open the tank: Generally, there are more than one fish in the tank, but if they are all dead, it means that the tank is still not open well. At this time, it is necessary to open the tank again. Take out all the equipment in the tank, re-disinfect it after emptying the water, wash it clean and then inject water to raise water, and pay attention to bacteria cultivation, and prepare a new tank fish to test the water.
