Need help with corals!!!

[Hallucination]

Hello. I have two corals in my tank that has been running for about 2 months and one cleaner shrimp. But today I woke up to something strange. My first coral (first pic) was opened up halfway at night which is strange because i have had it for 3 weeks and it has never done that. Also something else strange is that ive noticed something else growing behind my zoe coral. it showed up last night and when i turned the light on it went away almost instantly.

#2-3 look like Aptasia.

Yep...
In the future please turn the blue channels off/way down as many times proper color rendition is important with identification pictures..

We don't need to hallucinate when looking at pics..

Ok thank you. I will do that in the future. Is this something I need to get rid of?

You need to get rid of the aptasia

Definitely a pest, one that can sting/bother corals and easily take over a tank.
Exterminate them!
