Here is the damage the Glittering Charms did to the big plating acro. It should recover fine. I’m just glad all the corals didn’t sense battle and start chem warfare In the entire tank.Sorry to hear that. I had urchins once in a different tank that came in on live rock. I got sick of them rearranging my frags and had to donate them to the LFS. No urchins. No anemones, or anything else that moves around and messes with acro frags. I’ve got some big turbo snails that are “walking” a fine line of getting evicted.
