Why are my zoas disappearing

[keepingfishwithnoidea]

So i left for a few days and when i came back, over half my zoa colony disappeared, only 1 polyp was left, no signs of stress. Tank inhabitants were 4 tiny humpbug damsels, 2 baby crested sabertooth blenny, 1 possible hitchicker pistol shrimp, a baby coral banded, and a hermit crab. Ill send a picture of the zoa now when it opens up again. I took it of the frag plug and glued it today because there was a chance the glue wasn't strong enough and it just gpt ripped of from the flow

Any unwanted starfish in the tank? What are you water parameters? Any other zoa colonies in there that are fine/untouched? Maybe a full tank shot for reference?

Here is the coral now, its a little closed up because I just glued it directly on the rock instead of the frag plug

The anemone to the left is a huge manjano anemone that is on a seperate rock so it cant hurt my corals, I found that the bug ones dont sperate as quickly and I did take them from the ocean bc they are getting invasive around here

I tried zoa's with a coral banded shrimp and it ate them, I would bet on the shrimp in this case.

Oh okay, that was my tanks main creature too. And I thought they were reef safe. Did they pick at other corals such as mushrooms?
