Moving a feather duster

[Scavenger]

One of my mushroom rocks fell over during the night and was lying upside down on the sand bed this morning. To my surprise a gorgeous Christmas green and red feather duster tube worm was extended from the bottom of the rock. I'd like to remove it and put it in a visible area. My question is, do I have to break the rock itself or can I try to remove the tube area of the worm and re locate it??

Thanks in advance.
