At first I thought it was just some errant hair algae that got stuck to the edge of the frag. Now, its starting to grow and has turned really black.
The frag looks healthy otherwise, polyps extended and coloured nicely and has shown some growth (growing over the glue and expanding out the edge)... but I am a little worried.
Anyone have any experience with this before? I am hoping someone can figure this out while I go take a pic to post
