I just purchased a frag covered in real nice star polyps. This is my first experience with this coral. It hasn't opened now for a few days. Is this normal when there is a change in lighting or flow? Does it indicate a problem? Do these have a preference? What is the best way to get them to spread? I have visions of the whole back of my tank covered in star polyps, like a tank I saw at That Fish Place. How do I get there from here?
