For now let it be. Color is still good. Test parameters every day to stay on top of things. The most important thing to do is to leave the animal alone. How long have you had the anemone?
FWIW...the first thing you should do at the sign of any trouble is a water change.
Some people are like slinkies...they serve no real purpose yet can still bring a smile to your face when you push them down the stairs!:p
Have a great day! Brian
