I know when my MH shut down and there is only the actinic left, my zoanthids first close, then they reopen again as if nothing happened....then when my actinic shut down and the moon lights turn on, the zoanthids close up for the night. I guess that the less the light they receive the more they are closed in my system.

from my understanding they only open up when there is enough light for photosynthesis
