Emerald crab...

I was thinking about adding an emerald crab to my 90g to help get rid of a few small areas of bubble coral. I'm a little concerned because I heard that they can also pick at corals. I have softies,mushrooms,LPS, and zoas. Think I should "risk" it?

I have three in my 180. They will "taste" new coral when it is first put in but no damage has ever been actually done. Never had bubble algae but have always had emeralds so maybe that's why.

I have 2 in my 75 and they do a great job keeping the rocks clean, however mine dont seem to like bubble algae since I am starting to see more of it recently. That being said I have never had issues with them picking at corals, even when I have added new stuff.
