View Full Version : Zoas not opening. Help!?

02/10/2017, 03:09 PM
I am new to this page but have had reef for many years then took a break and recently got back in it. Have several corals all doing great! Then bought a few large zoa rocks. They were awesome the first few days and now on 2 of the rocks most the zoas won't open and I'm noticing there seems to be getting less and less on the rock. Is something eating them? Can I do a FW dip? Or a coral dip? Any recommendations would be helpful!!

Are these the first zoas in your tank? There may be too much lighting for them so they are melting away.

Do you have a lot of Asterinidae?
They love to "eat" Zoas
