Wow. that's good to know. The Zoa will be gone but does it have tentacles to kill the adjacent frogspawn and hammer?Bubble corals are very aggressive. You should put it in the sand away from other corals. That zoa will get killed. Everything on that rock will get killed. Put the bubble in the sand and it will be happy
I have it wedged between the rocks there and will be easy to remove. But really want to keep it on the rocks.
