When I first saw this a few days ago it was a little smaller and I thought it was some old super glue where I had removed a coral a good while back. Part that got my attention was that it had a yellow green fluorescence. (under Ecotech SB+ default daytime spectrum).
Now though it appears that it is something....alive... and I'm not sure what it is. Help please and is it good or bad?
