Is my Rock Anemone okay?

I bought a healthy red and grey (I believe. It doesn't look the same anymore.) Rock Anemone last week. I floated it in the bag for an hour and drip acclimated it for 2 hours. Right after I put it in the tank, it immediately changed color to dark brown where the red used to be and light brown everywhere else. It still looks the same as when I first put it in the tank last week. I know it's not dead because it closes itself occasionally (Not sure why it does that) and opens back up.

Can someone help me out here?

 

Most likely your lighting made it appears as though the anemone was a different coloration. Anemones do not change coloration swiftly, put it under the same lighting it was under and it will appear red and grey again.

Anemones typically exchange water/fluid. This remove bi-products of metabolism/waste and assist in gas exchange. This is a normal behavior by Anemones.

As always an image is a big help with trouble shooting.

 

Okay, thanks for the help! I'll post a picture in a bit
