Can I feed my marine fish with grocery store uncooked shrimp?

hey guys,
I would like to know if it is ok to feed my marine fish with grocery store uncooked shrimp?
I live in Republic of George, and here it is really difficult and very rear to find and the buy frozen fish food, therefore I was wondering if it is ok to buy frozen uncooked shrimp in my local supermarket and feed my fish with this? if yes, can you please give me the instructions how to prepare it before I give it to my fish?

Do I need to defrost it? do I need to wash it with RO/Di water? Do I need to blend it before I give it to fish?

Please give me step by step instructions.


Thank you in advance!
