As far as I know pistol shrimps will not harm cleaner shrimp because they mostly remain on the sand bed and the cleaner shrimps live under crevaces.

I had my pistol shrimp in my refuge with sand and aragonite mixed, they constantly rearrange the tunnel and surrounding areas where they live. It won't be a problem keeping it in your tank. They kinda remind me of a bulldozer in an excavation site where they constantly bulldoze back and forth. Very active buggers!!
