You could try some sort of crab....
Not sure what a puffer wont eat...they do like to eat inverts. I had an Arrow crab with my Porcupine for a while, but as soon as puffer could fit it in his mouth, he did. Perhaps an bigger sized emerald would work...? Or maybe some larger hermits.
....All depending on what else you have in the tank.
