Pistol and Cleaner shrimp together?

I purchased a red Pistol Shrimp a few months ago from my LFS. At that time, I was told (by my LFS) that it would be safe to add a few cleaner shrimp whenever I was ready. However, I just viewed a video on u-tube that shows a Pistol Shrimp shooting a Cleaner Shrimp, rendering the cleaner unconscious then taking his victim into his lair to eat. Do any of you have both shrimps in your tank? Any problems?

 

I have a tiger pistol, 2 cleaners, an emerald, and a porcelain crab and never had any problems. They walk past each other all the time and no issues.

 

Its a risk.... theres no doubt about it.

 

It's a risk, but a relatively small one. Pistols and cleaners occupy different niches on the reef, and the cleaner likely won't ever hang out at the bottom of the tank where the pistol will have a burrow.
