Help with Identification

Can someone tell me what this is next to my Sympodium blue frag? I saw it this morning. No lights on yet. Is it something I should remove? I have all softies in my tank.
Thanks!

Is it moving around or always in that location? If you touch it does it feel like it has a hard skeleton? I'm guessing it could either be a volunteer stoney or soft coral or a nudibranch of some kind.

Looks like a nudibranch of some sort, some are known to eat octocorals so I'd remove

It is soft. I have never seen it before this morning. So, it must be moving around. Should I remove it?

Will do. Thank you so very much.

If it is moving around it's almost certainly a nudibranch. But they are pretty cool animals and I'd keep it myself. They are species specific preditors so you would have to figure out which species it came in on to keep it alive. Even then they are pretty short lived so it's unlikely you'd even have it a year.
