An aquarium has lonely eels. The aquarium is in Tokyo. It has many garden eels. Eels are usually shy and stay in their holes in the sand. The aquarium eels were used to seeing visitors and stayed above their holes. Staff are worried the eels are getting lonely because the aquarium is closed. The eels may forget what humans look like.
The aquarium will re-open after the coronavirus emergency ends. The eels could get stressed when people visit again. The aquarium tweeted: "They aren't seeing humans so they are forgetting about us....Could you show your face to our eels from your home?" The staff want eels to know that "humans are friendly".
