Welcome!!! I love watching my clowns and anemone interact. It is wonderful and should be a very long term relationship. So, you need the time to make sure it happens positively. What kind of anemone is that? Look kind of like a Condi and most clowns do not get hosted by those. Otherwise it may be a bleached nem and we need to help get it healthy with you.
First off, make sure your parameters are in line. Nitrates can be a bit higher as phosphates can be readable too. Make sure you try feeding the nem some giant mysis or similar twice a week.
You will enjoy this exciting hobby ("way of life")! Take it slow and ask questions if needed. Never think it is a stupid question. We have all been beginners.
