Puffer Problem

[usatennisfan]

So I have had a Lantern Toby for about three months now and I must say I absolutely LOVE him. Not my first puffer but Norbert is my first saltwater puffer. Recently he has been refusing to eat any live hermits or snails and I'm really starting to worry about his teeth. I feed the system at least four times a week and every time he goes straight for the krill that I thawed. I was under the impression that the carapace on the krill would grind down his teeth enough to keep them from overgrowing. Any ideas on a solution to this plight? Any other foods I can feed him to help keep his teeth worn down? Any help would be greatly appreciated.
Thanks in advance,
-Stephen-

Can you get hold of half clams?
