Help please!!!

I'm getting nervous because both my zoanthids have been closed for 2 days now. Ever since I shut the light on the tank over night(10 hours) they haven't opened. Pleas help fast!! But also I saw a little thing on my Zoanthids and I assume it's a hitchhiker that eats the Zias so I got it out and flushed it. But what if there's more? How do I get rid of them?https://gyazo.com/f8f63e071208c65aa951f6976871cf28 Is there anything that needs to be moved??

I would post this in general reef discussion, will get a much faster answer. This isn't exactly propagation.
