In one aquarium which has the largest tank in Asia, there are Spotted Eagle Rays that show stereotyped behavior. In a documentary video, the Spotted Eagle Ray is free in the sea. They swim as fast as a jet, or gather in groups to swim in a straight line. It looks completely different from the same breed in the tank that shows stereotypical behavior. The book <Aquarium> shows the cruelty behind aquariums through the appearance of Spotted Eagle Rays deprived of freedom.
