What is this? seems like a Nudibranch?

I am most likely wrong, it releases mensenterial filaments, so I guess its not a Nudibranch?

but the antennas are quite similar, Can anyone help me identify this?

Need a youtube or .mp4 video to be able to see it. Just upload as a yt video with an account or go to a website like free convert.com to convert to .mp4

Reefing is equally beautiful and terrifying. +1 for Vermatid snail.
