I had to do some rearranging of my tank yesterday so I took the opportunity to give my GSP Chia Skull a bit of a "haircut". The Green Star Polyps had completely grown over the eyes, nose and teeth on the skull, so I took a razor blade and cut a new hairline, and peeled off as much of the GSP mat as I could. You can see from the before pic how nobody even knew it was a skull, just thought it was a rock covered in GSP.
