col I heard exacto knife also, and some super glue gel (if you want to try to keep them).
NMReef When I first started I bought what the LFS told me was a LMB. Had a nice bunch of yellow polyps and they disappeared---saw that the "imposter" was the culprit. Remove it and put into QT, did some research. Ended up to be an Ember Blenny, cirripectes stigmaticus. That was the only problem I had with it, but I had no other corals at that time. Look up them, it looked like the LMB just all black and I think blue spots if you looked close enough.
