Berghia or Monti Eating Nudis?

[returnofsid]

I've noticed several very small nudibranchs, on a couple Montipora caps in my 75. However, a few months ago, I did introduce a couple Berghia to that tank. Can anyone tell me a reliable way to tell if what I'm seeing are Monti eating Nudis are juvenile Berghia? I just pulled several off and have them in a container, while I try and figure out a way to get a good picture of them. If I'm able, I'll post a pic.

see any dead spots?

Dead spots on the bottom of M. capricornis are quite common, due to lack of light. However, since starting this thread, I've had confirmation that they are indeed Monti eating Nudis. Grrrrr. Time to start dipping and QTing all my Montis.

Yup, it looks like a monti-eating nudi. Many nudis have very specific diets, so if they are hanging around your montis, chances are they are eating them.
