From that view, I can see nothing wrong with him at this point. How was the foot in particular, you can usually see if something is wrong within the foot area first? I would say just stay the course with him, especially if one of your clowns is hosting, that will only help him adjust to your tank and the new environment. I wouldn't necessarily confine him to one area, it may be that he wants more or less light than where he is, so don't get him stuck in one spot, let him decide. The clown should also take care of most of the feeding for you. The color and extension look great, that is one nice looking anemone!
