Injured Anemone - don't know what to do

I have just added an anemone to my 24gal Biocube so my maroon clown would have some company. It seemed to acclimate well on Day 1, fed some squid on Day 2. He footed himself on Day 1 then decided to unfoot and move. I did a regular scheduled water change and some tank maintenance which didn't seem to bother him. But overnight on Day 2, he floated up and got stuck in my Koralia power head. I shut off immediately, he sunk to bottom and has been there for two days. His tentacles are once again expanded, no dead anemone smell to the water, this is second day still alive. But today, it looks like he has big water blisters on his orange base which are white. He body is all stretched out, has not refooted. I have left all lights and Koralia off as not wanting to stress more. Any suggestions?

 

I would leave the lights on regularly 6-8 hrs/day.
Once it fully opens up its mouth wide and white, stringy cottage cheese looking stuff comes out, then it's about dead for sure.
Can you provide a picture of your anemone as it is right now?

 

watch it closelly cause if it dies in a 24g it will nuke it and all you have in it. can you quarintine . good luck and i really hope it makes it. this is what it looks like if they get cut. this one died 2 days after pic.

 

like stated above. keep a close eye on it.
