I just found some on a recently acquired monti frag. I put it in a dip with "revive" (because that's what I have) and used a large glass dropper to blow them off, then I scraped with a razor to try getting as many eggs as possible.Really? Proposed fixes? Surprised honestly. Only have 2 Montipora in the tank. Both have been there for about 2 months. Never got any growth but never had any side effects either.
Try to separate the coral from the frag plug and blast water underneath to blow them off because they can get under there to hide.
I found this video that helps a little
