Are these bubble tip anemone stings on my Duncan?

[The Coug]

Hi all,
I’m new to reefing with a stocked used tank I recently bought. I just re-scaped the tank and one of the anemones is now close to the Duncan. After a couple days the side of the Duncan started to retract and seem unhappy. I turned the Duncan 180 degrees and moved them further apart. The injured side has had retracted tentacles the last 4+ days or so.

Questions:
-Is this damage likely anemone stings?
-Is there anything I can do to help heal the Duncan? Are they far enough apart now?
-I’ve now got kinda of a open space on the rock, any corals out there that can tolerate anemone stings?
-Suggestions on how to just removing the anemone?

Any advice is appreciated!

I like your scape. Yeah, nem sting. It will likely heal up fine unless it gets stung again. As for removing... you can kind of corral it with smaller rock until it decides to move onto one of them and then remove it. You can patiently massage and kind of slowly pull the foot away from the rock, and you can gently massage the foot with an ice cube and it should loosen its grip. Don't freeze it just chill it.
