    Based on that damage to the monti's on the pic I would suspect Monti Nudis. They can be hard to spot because they primarily feed at night and they are only about 1mm long. Are you able to take macro shots of the coral? Best would be done right when the lights turn on. You might catch them in action. IME, they leave behind a detritus trail which actually makes them harder to see.
