killer coral banded shrimp

[drksails]

I came home the other day to see my CBS with my royal gramma in its mouth, eating it. The CBS has also eaten a cleaner shrimp, and a fire shrimp. I think its about time for the CBS to go. Is this normal for this species I've heard that they are very aggressive but killing my Royal Gramma?
