It's a friend, to the extent that it is part of a cleanup crew...but if you get too many, some people don't like the sight of them. If you get too many and want them gone, I hear a six line wrasse will eat them. I believe my red coris wrasse must be eating mine, cause I have a 220g display with over 350lbs of rock and I have seen one in a few months.
As for stinging, it's a very minor sting. In fact, you probably won't even feel it. however, I recently cleaned out my refugium, and in the process, had so sift through it in areas I couldn't see....and must have gotten stung many times. For about 4 days, my hand was just barely swollen, and tingled. I'm thinking I got many stings and they all added up to do this to me. It went away, and wasn't ever painful...just annoying. :embarassed:
