My fish, Tango, jumps and responds to his name too!
I taught him to jump through a hoop. I held the "hoop" (a plastic braclet) by submerging the hoop 1/2 inch, and holding food for him to get. Eventually he learned to jump through when it isn't touching the water.
Although it might not look to proffesional because his fins drag once his body it through.
