Do corals normally close up at night?

[Datreeferman]

All 6 of my corals close up/shrivel/shrink at night time. Is this normal? As soon as I wake up they're all open again. I have a torch coral, Kenya tree,mushroom,Xenia,zoas,and a candy cane coral. I have no lights on at night and all my params are good. My torch will sometimes open at night.

Perfectly normal! I have a torch, a bunch of zoas, and used to have a kenya tree aswell and they all do that except for the kenya tree, it didnt.

Pfewww! Thx for reassuring me, I thought that there was crazy fluctuations at night or somthin ya I just checked my Kenya tree. It doesn't close up. I just looked at my other corals and assumed that the Kenya did too. for the help.
