Anemone questions

[FrostyToast]

Hello!!

I’m new to saltwater tanks and I decided to get a LTA for my pair of clowns I’ve had for a while.
I’ve never dealt with nem’s before, so I want to make sure I’m doing everything correctly. I even added some more rocks for it to attach to or hide behind.
Here’s it a few minutes ago, earlier today it was attached into my substrate just fine, but I just checked on it and it was unattached in its side.
I know they like to move around the tank but I just want to make sure it’s just trying to move and or reattach and nothing more serious is going on.
I added it in roughly 3 days ago. Thursday at 3 PM after drip acclimating it for an hour and a half.
It was more purpleish in the store, so I know it’s stressed but it hasn’t been loosing any of its color.

Here it was roughly an hour before lights out

My cleaner shrimp have been picking at it from what I’ve seen so I’ve put them in a breeder box temporarily to try to avoid anymore stress for the nem.
