Help with new zoas!

[blennielove]

Hello there,
I just got some mail ordered zoa frags and they arrived on Friday. I've acclimated them and placed them in a quaranteen tank (8 gallon nano with stock lights) and half of them are opened and half of them look...well, closed. I was wondering how long should I quaranteen them and if I should fresh water dip the ones that are closed?
Thanks!

You should dip all of your corals before they go into the main tank and really before they go into QT. They take a while to open sometimes depending on the polyp and the condition they were in before they were shipped. Can you post a picture? I wouldn't freshwater dip either. I use Revive coral cleaner and it works very well.
