Roller Coaster Nearly Die Fish

Below is the video of the roller coaster nearly die fish. 
In this morning, before I go to my school, 
I found it almost die and it start to become roller coaster. 
I did not care it, cause I cannot control its dead. 


After school, I thought that it was already died, 
but it still swim and roll. 
So I take video and share with all of u. 
The video quite long, 1&41 minutes. 
The fish stopped to roll due to no energy at 52 minute,
1&20 minutes and at 1&
04 minutes one alive fish slightly touch the almost die fish and the die fish roll again.
