Came home after being out awhile today and my Green Star Polyp is completely retracted. Its never done this before. It came with a piece of halimeda attached to it. While I noticed yesterday what I thought was possible algae of some sort, after explaining it to my lfs guy he pulled a piece if halimeda out and showed me that it's actually just their "footing. It looks like the "foooting is growing over the GSP. Below are some pictures. I know there not the best.
Well, after some surgery and some glue work, my GSP is happy again. Took a couple days before it fully emerged but it now seems happy. I had to go pick up a small piece of rock to glue it too as the halimeda was holding it in its previous location.
