A single PBass is harder to pellet train. . I always use 2 little Oscars to help train the bass . And it helps to have 3 or more little bass.
There's a good sticky on how to teach your bass to eat out of your hand ,it really works . It's in the PBass fourm.
I start my little bass on chopped up earth worms. I rinse them off in a small net. Chopped them up just small enough to to eat easily and still wiggle ,and rinse again. Dump the worms right out of the net or drop them in with your fingers.
The first time will scare them. But in a week thy will be coming up to the top of the tank attacking the net or taking food from your fingers.
After they are eating the worms really good drop in other foods with the worms.
