If you got this in your gulf/keys rock i would imagine this is much less aggressive then the imported fiji rock. Mike (owner liverocks.com) keeps these guys in his reef tanks. He says the key is to just keep them fed, he has never had an issue with it being bothered, more his damsels and other fish beating up on it.
I as well have 2 pistol shrimp that i hear popping all the time in my sps
/clam tank. Never had an issue with them.
Good luck with your tank,
