Help with this critter

so tonight right after my Halides cut off, I noticed this on my glass. About 3/8”. Appears to be some kind of nudibranch. Friend or Foe?

Get it out! If you didn't put a known reef friendly nudi in, it is most likely a bad one

Ouch. Get it out for sure. There are plenty of good one's but they almost never come in as hitchhikers. The freebies are often the baddies.

My guess would be zoa eating nudi

Thank you, I removed him!
