Hey David, haven't heard from you forever! You can have whatever you want for free!
sorry I haven't gotten back to everyone sooner, I have been on vacation for the past few days.
the "green stars" are green star polyps. I don't have too much of this available though, probably only 2-3 square inches that just grew onto the sand. I have enough xenia for all though. The other thing that I have are green/brown Palythoa (at least i think so, these are sometimes called sand polyps). I have a couple small frags and then a bigger rock. I will post a pic of these later.
Would you guys be picking this stuff up at my house?
here is a pic of the gsps:
