Yellow watchman goby with blackray shrimp goby?

[CPdude]

Hi everyone, I currently have a yellow watchman goby who most of the time spends it day under a rock on the left side of my tank. I really want a pistol shrimp for him but I can't really seem to find one. So recently I went to my LFS and saw a black ray shrimp goby and a tiny randall pistol shrimp(about half an inch) pair for sale. I was really interested but the thing is, they are both small and the yellow watchman is probably able to eat them both if they were to encounter each other. I also have other inhabitants like banded serpent star and 2 pyjama cardinal that may go after the tiny pair. One thing about my YWG, he is actually quite friendly, he shares the rock with my lawnmower blenny and does not mind my shrimps, glass cleaner and longnose shrimp no matter how near they are. Should I try to release the pair into an area with more liverocks and away from the YWG if i ever get them? Any advice? Thanks!
