Rock with more inhabitans

[bok]

Hi!
I purchased a rock with a Rhodactis . But besides Rhodactis are some Xenia (I presume...) and I saw one feather duster.
Those Xenia, looks nice, and I have other types of Xenia in my aquarium, but I would still like to also have this new kind . Also , the feather duster is cool. Small , but cute. It is only visible when Rhodactis eats or is disturbed and crawls, so underneath I can see the small feather duster.
Ok, now... The Xenia is getting bigger every day, I the rock is full. Can I remove it and also remove the feather duster , but leave there the rhodactis ? Can I pull out the rock and try to remove xenia with a blade and maybe glue it somewhere else ? And leave the rock only for Rhodactis?
I will attach two photos to see how quick the xenia grows.... Pictures taken like a week apart

Upon arrivals in my tank :

looks more like anthellia or cloves or pipe organ...hard to tell without being able to see the base.

i would llikely try to cut the mushrooms off and let them fix to new rocks...but i dont have any experience moving rhodactis mushrooms...

I was thinking anthelia too. One word of advise. Put anthelia high. It will grow and cover everything but seems to only grow upwards. It doesnt seem to grow down. They also are a very good water cleaner and thrives on "Dirty" water. Since i put an algae scrubber on my tank, the anthelia doesnt look good not which i dont mind as i have tons of it.
