鱼缸的鱼这几天都不怎么动，我看了一下，也没有生病，但是它们在一边不动，又一条还睡在石头上面，最后发现原来抽水的水泵的水管掉出来了，装好好，它们又开心的玩耍了！The fish in the fish tank didn't move very much in the past few days. I looked at it and I didn't get sick, but they didn't move on one side, and one still slept on the stone. Finally, I found that the water pipe of the pump that had been pumped out fell out, and it was well loaded. They are having fun playing again!
