Zoas do they close at night?

[chris31]

Just like the title says do they usually close at night?

when I had my tank set up they always closed at night. How long have you had them in your tank? are they opening during the day time?

Some zoas do, some don't.
Palys normally are open.

Mine closed at night at first. the longer i had them in my system the more they will stay open at night.
