Genghis Khan is healthy.

In addition to being frightened, each Han shark has a different adaptation time. The darker its body is, the more normal it is. When its body is white, there are many little tricks. Sometimes it stands upright, and sometimes it swims backwards. At this time, you should pay attention. You may swim and fall to the bottom of the pool. At this time, you should hold it on the water with your hands until it can swim normally, and then observe it for half an hour. It doesn't matter if it's normal. If not, you must put it in a smaller tank and swim without oxygen. When heated to a temperature above 28℃, the current should not be too fast, otherwise it will scare it. But then it will hit the tank and swim in circles instead of in circles, so it is not far from death. The ability of Han sharks to come back is really strong, as long as they don't get sick, even if they are stunned by electric leakage. You can pick it up, touch it for a while to make it regain consciousness, and swim for a while, and it will be fine. Just watch it swim in circles without wiping the bottom of the cylinder. Write so much as a reward. Although typing is a bit messy, I may feel dizzy. sorry
