I had a camelback shrimp 5 years ago when i first started in this hobby. I noticed some of my mushrooms were disappearing and found it out to be him. In my honest opinion I would never have a camelback shrimp or peppermint shrimp in my tank with corals. But this is just me and other maybe just fine with them in their tanks.
If it were me i would definalty get rid of him and get yourself a skunk cleaner shrimp...
