Is my anemone dying?

[Jorge FG]

My anemone seem to be doing good but the last couple of days it has been a little down. Yesterday afternoon it was like this and hasn't "come out" since. Is this anemone dying? First pic is a couple of weeks ago.

My parameters are:
Amonia: 0
Nitrate: 30 (have been struggling with this)
Phospate: 0.1
Calcium: 410
Alkalinity: 8.3
Mag: 1290
Salinity: 1.023

I have one AI Prime HD, my tank is 60cm/23" by 40cm/15".

This was today

It’s closed but not dying. If it only been closed since yesterday there’s nothing to worry about
How long have you had it for ?
How old is your tank ?

I've had it for 2-3 months, my tank is 9 months old.
