Anemone Help!

My anemone hid under a rock the first day I got it parameters are fine don't think he is starving. Moved him up to the location he is now in the picture he seems to have shrinked don't know what is going on.

Are your lights possibly more intense than what it was used to at the store?

It's kind of normal for them to hide for a few days. Shrinking is normal at night and also after eating. Post pictures please.

So I've got a gbta and it lookes pretty healthy.
For it home from the lfs and it had good color but looked a little sad and was not sticky.
About a week later he looked grate, sticky readily accepted food very reactive.
Fast forward a couple weeks and my anemone lookes as though it's been pruned I'm assuming by my clown that hosted but it's missing substantial tentacles.
They are growing back and look healthy and properly colored, problem is the nem will react and try to eat but it's not sticky, should I just continue to try to feed occasionally and assume it's bacteria will take care of it or try to get some brine shrimp directly in its mouth?

Parameters are normal and stable dealing with the onset of some red cyano after switching to led lighting though .
I know nems are weird critters I'm just looking for someone's 2 cents lol.
