Zoa Eating Nudi?? Help ID PLZ!

[special-ops-s2k]

Hello I found this critter on one of my Zoas in my coral QT tank today. I immediately removed it and took these photos... I think it might be a Zoa eating Nudi? Please help me positively ID and if possible suggest my course of action going forward? I assume a schedule of dips to try and break the life cycle of this pest? Thanks

Winner winner chicken dinner! Get a wrasse and dip those baddies , your gonna have to keep inspecting and cleaning for a few months . it takes like 3-4 weeks for eggs to hatch then like 4 more weeks till they are visable size.

That's what I thought. I have other corals in the same QT... I'll dip them all of course but will I need to be concerned about these being on the others? I was putting them through 76 day fishless QT to protect against ick and velvet in the display. I don't mind keeping them all in QT longer just want to know what to expect
