SYNCHRONIZED GOLDFISH!

I'm having a bad day, and trying to relieve the stress with all these animal videos.

There are some rumors that there are magnets in the fish or they are controlled by electric currents. Because it is general knowledge that goldfish are dumb, so nobody has faith that these goldfish can do amazing tricks. I don't know whether to laugh or cry...

The guy refuses to tell anybody his trick to this aquatic performance.
