Awhile back, someone asked how to teach your betta to jump.
Well, i just succesfully taught another fish.
It is really simple. You just let him see your fingers drop the food.
you know he is ready to jump when he will see you reach for the jar of food (or open his tank) and he will swim to the top of his tank to wait for food.
Once he starts waiting at the top for it, you just hold it infront of his face without dropping it.
He will get impatient and jump for it.
:) works for me.
