Why did you start flying out?
The morning has not been understood.
It is because of the experience to the usual rage.
When it returned from the company and it peeped in the water tank,
the eel was dead.
It has Gaccaried it.
The oxygen deprivation.
Therefore, I thought that it had tried to escape from the water tank.
