Months ago I bought maybe an 8 pound bag of frozen cooked cocktail shrimp. It was $25 and I brought it home and to my surprise they were shelled and not deviened. I cannot eat shrimp pooh and hate deviening shrimp so I started peeling off the shells and feeding the to my pacs. Not only have they grown big and strong, but they love em! In my opinion it is the cheapest way to feed frogs. At the rate the bag is going it will last for many more months. Just wanted to share
