Saddle puffer fish help!

[dekfish]

So i am about to get a saddle puffer fish. I've done the research and understand that they need something hard like clams to grind there teeth down. I have having trouble actually finding feeder clams(if thats such a thing) is there a site that i could get them or is there a great alternative for clams?

Just go to your local grocery store and feed it fresh shrimp (in the shell), clams, etc. Works like a charm for my c. papua.
