What kind of damage is this?

[BrassMonkey]

This happened overnight, wondering what did it so I can takd corrective action. this frags ugly, but i dont want it to happen to corals I care about.

A pest would be my first guess. Crab or worm?

 

[M007]

I would agree, crab most likely. :headwalls:

I have a emerald crab and two peppermints. guess it coulda been one of them. I will tolerate it with the emerald cause he does a great job, but will batter and fry the peppermints if I catch them. Thanks

I’m sure it was either your emerald or pep shrimp. I personally seen an emerald eat my sps polyps.
