Is this good or bad?

[not_eman209]

I didn’t see where this would fit, so hopefully I can get an answer here, I was redoing my aquascape and I found a Zoa frag that my shrimp took to his burrow, and noticed it had like a hollow nest thing on it, i saw it on a torch frag also, on its skeleton. Any clue what it could be?
