Palythoa acting weird!

[My120gmixed]

I have two large colonies of palys along with other developing clusters. Yesterday I fed them all a sizable portion of meaty food. I know palys don’t need food but I like to feed coral every once in a while to promote growth. Today, I noticed one of the palys in my largest colony wasn’t fully open... is this a bad sign? Will palys in larger colonies occasionally close? Right now my lights are on blue so all of the palys are going in for the night. Can someone explain how Palythoa and Zoanthids normally behave?

The particular paly could have caught a larger piece of food and will stay closed until it consumes it. Hard to say but sounds like a typical feeding response

water change and go from there,,usually when my palythoas act up,,I do a water change and most times they open,,if that dont work in a couple of days then increase flow alot more,,,Alk swing ??
