I have a weird issue that seems to be going on with my Xenias. On a few of the polyp stalks, it seems like there is some banding going on or something. It kind of is hard to tell from this video, and a little hard to get a good pic of it, but you can kind of see it in the middle polyp in this video. Almost seems like it is bent too much, but flow seems pretty good in that area of the tank so its not going crazy. Thoughts?
