These goldfish seem to be swimming randomly when all of a sudden, synchronicity takes place. They start to swim the same direction as if coordinated and choreographed. As you watch on, you will see a man waving his hands and it seems that these motions dictate to the goldfish the direction to swim. This is nothing short of amazing!
Moments later, the goldfish take on a certain formation.
