A fish at the Vancouver Aquarium has received a prosthetic eye after in-house vets noticed it was being bullied because of its missing eye.

Humans and fish don’t seem to have much in common, but there’s one bad behavior both seem to exhibit in enclosed quarters--bullying.

The kind of opportunistic behavior it experienced, including having food stolen from its blind side, is a typical way for animals to take advantage of others’ weaknesses and secure the best resources for themselves.
