Favorite zoas doing an umbrella

[whitasm]

Can someone explain to me why my favorite zoas in the tank would be doing this umbrella like thing. It’s the only zoas that are doing it and I have over 8 different frags. I’ve turned up the lights a bit and it just seems like the 2 other polyps started doing it too. Don’t wanna lose these guys. Thanks!

They will do that. Mine do the same and recover..

Gotcha, so it’s nothing to be alarmed by? They’ve been doing it for a week or two now but I’m seeing another polyp come up so I’m assuming they’re healthy.
