Time Lapse of my Zoas Pulsing --- But why?

They are not pulsing. It looks like when you present a time lapse video though.
They can retract and that could be because of many things.
Normally it happens when they are catching particles from the water or there are some small organisms touching them.
If you touch the stand...
Fishes coming close and making some shade could do it...

They are not pulsing. Sorry. Unless they do that all the time regardless.
I know that's probably not the case.

Let me know if I'm wrong.

It's good to see a zoa video anyway! :thumbsup:

Grandis.
