Corals during the night

[Mercury64]

I am new to corals, all my corals are do great at this time, have had them about a month now
What I did notice and find odd is when the lights are off some of them like the bubble coral or the open brain tend to look like a decaying dead plant
when the lights come on shortly after the look perfect in every way, I almost thought they were dead ,again im new to corals so I just thought that was kind of weird, in fact the only thing that tends to stay open 24 / 7 is my flower potts
My button polypes-other polypes-brain and pagoda cup coral all tend to close, the bubble is weird, sometimes it closes someimes it stays open when lights are off
Its a little scary when your new to corals, I find my self always looking and checking on them

Well im learning ,boy did I panic when I saw that, I said to my wife I don't know what happened, they all died ,they all looked great 10 minutes ago before the lights went off, turned the lights back on when she came to see what I was talking about they all came back to life, thats when the light when on in my brain and I figured out must be because the light / sun went down

the aquarium at night is a very cool place. Some corals are nocturnal feeders. After lights out they will extend long sweeper tenticals to capture food.
