Will a Porcupine Puffer fish eat a peppermint shrimp?

I have a saltwater tank that has been up and running now for about 8 months. I put some Tonga Uaniva live rock in the tank. It is a 75 Gallon with just over 100 lbs of Rock. I am having a problem now with the Aiptasia Anemone and i'm wanting to buy a peppermint shrimp to help rid the problem, but i'm afraid the puffer will eat it. Any help would be greatly appreciated. Thanks in advance. Also I just added the puffer about a week ago, don't know if that is relavent but thought i would add that. THanks again.
