Ornamental goldfishes are very graceful creatures that adorn home aquariums world over and you could watch them swim about and destress after a hard day of work. But a firm called R2 Fish School have some different ideas. They claim to train your goldfish to perform a plethora of tricks to entertain you and even have designed a kit to sit in your aquarium. Goldfishes hoop a ball across a watery ring, or even swim around obstacles. If that is not insane enough, how about your goldfish doing a limbo or even playing David Beckham and bending the ball across a very wet goalpost. Phew! And In the process of doing all this, they manage to look like aggressive sharks rather than calm and peaceful goldfish that you used to enjoy watching. Don’t believe us?
