Anemone question

[Ben10]

So I have a condylactis anemone, and when I got home from school today, it had burrowed itself into the substrate as far as it could, which isnt really that far, just wondering if I should be concerned. It looks healthy, just a little curious. So if you have an idea that would be helpful. Also the tentacles closed but not dangling.

By the way
Ph is 8.0
ammonia is 0
nitrites are 0
nitrates are 10
and temp is at 78 degrees

They are normally found with their base buried in sand or rock crevices.

I know, but the base is stuck to the glass, and some of the tentacles are in the sand its like sideways

It should be fine they like to move around all the time though

How long have you had it? What lighting is it under?
