white roots like thing on my Zoas

[MaxSmile]

Hello All!
Could anyone help identifying this?
Zoas feel fine, always fully open, today I fed them and only saw this when they closed. it is all underneath the heads, all around and growing all around. I have not noticed it a few days ago when I fed them.

That was my very first coral and the only one affected, I do have many other zoas that look great with no signs of this monstrous thing.

Thank you in advance!

Do they move around if disturbed, or are they stationary?

Thank you Kj,
does look like it. Never stop learning.
It is stationary, does not move or retracts, and it grew fast surrounding zoas like a spider web.
I just read it is toxic, I guess might be problematic to remove it...
