Nudibranch found in SPS system - ID/Question

[Sierra_Bravo]

This nudibranch came off an acro frag I had given to a local reefer. This looks like the pics I see of zoanthid-eating aeolid nudis, but my system has zero zoas and is 95% acros/other SPS. Anyone seen or had experience with finding this type of nudi in an acro tank?

It's a well established 7 year old system, I have not added corals in over a year, and I can see no apparent damage to any corals or signs of infestation. I dipped the other frags on the rack it came from and the two colonies I took the frags from and have found nothing else.

Thoughts? I'm not sure if this could be a benign nudibranch that inhabits my system. I don't want to be a source of pests for my community, obviously, but at the same time I don't see any type of issues with my corals. It would be great to hear from anyone with similar experiences or opinions.

Certainly looks like a nudi.

Any monti's in the tank?

Yes, several that have been there for years. No tissue damage on any of them and they were not near these frags that the nudi came from. I've found multiple pics of monti-eating nudis and they are quite a bit different. Here's two examples:

Oh I know what they look like, dealt with them myself a few years back.

It was just maybe an AHA moment, and not something you may have thought of.
