Why did my sea anemone move

[tp1011]

I have had this sea anemone for about two months now and he has stayed in the same place the whole time. I have a kessil 350 and turned down the blue spectrum all the way yesterday to take a few pictures. I forget to turn it back up, and maybe he did not like this and I found him in a different spot.

My other sea anemone did not move and he is at the top of the tank the one that moved is close to the bottom (he moved a shady spot)

Why would he move???

P.S. all my peramters are in check.

Anemones will move for any number of reasons. To get more light, or less. To much flow or to little. Searching for a spot with more food or just a change in scenery.
Impossible to say for sure.
