I've had this nepthea for about 7 months, and it has been growing well. However, it's in an area of low light and is leaning to get ot the center of the tank. I'm working on redoing the lights to give it something more direct in that area of the tank. When I got it from the LFS, it was on a frag plug. I popped it off and glued it to a rock with super glue gel. It was the first coral I glued, and it didn't come out the greatest, so I built up around it with 2 part epoxy putty to make sure it didn't fall over. You can see in the before picture that there was a "crusty" chunk at the very bottom of the frag. That wasn't at all visible once I built it up with the putty, and I didn't see it again until about 3 weeks ago. Now, it is creeping up the stalk of the nepthea and is black on the back side. Should I cut this off the rock and re-attach it? What's the best way to re-attach it if glue/putty is causing this? Rubber bands or a screen of some kind? Thanks.
