2fish dead coral banded shrimp to blame?

So I had a clown and a firefish in my 14 biocube. They had been in the tank together for about a month and seemed fine. I then added a coral banded shrimp and abd shortly there after my firefish died. Figured it was just coincidence... But now my clown is also dead. He seems to have got pretty torn up. When I checked on the tank 10 hours befor that he seemed just fine.



So do you think it was the shrimp?
