Good Nudibranch?

[ClownWrangler]

Found this crawling on my glass. It's definitely a nudi, but is it a good one or a bad one?

Does not look like Berghia to me, so likely something bad. Would always be cautious around these guys.

Yea, I just looked it up. Unfortunately it may be a monti eater. I just started my frag rack a couple weeks ago but didn’t have dip on hand. At least I caught it before I had a whole reef tank going. Will seachem reef dip take care of any that might be on my frags, or should I use something a bit more harsh like potassium permanganate?
