Many store bought shrimp are raised in crowded fresh water ponds. These can be harbingers of bacteria and other parasites that can harm our fish. Cooking them first, eliminates this variable.
^ Why boil it? since even lightly cooking it will cause the shrimp to lose some nutrients...
I feed all my puffers (past and present) raw shrimp and never had a problem thus far...
I killed my STdatnoid w/ raw shrimp. Ain't takin chances anymore
