Here is a tip didn't make the manual or training DVD that are included with the soon to be available R2 Fish School Training Kit.
The basketball trick, where your fish learns to push a tiny floating basketball into a hoop near the surface of the tank, is cool. But the ball has a tendency to float away due to the current from the pump. To make it easier for your fish, you can temporarily turn off the pump/filter during basketball training.
Just don't forget to turn it back on when your training session is over!
