i have a colony of pink zoas (or they may be palys) neways since yesterday the colony has all closed up and stayed closed. I have other zoas in the tank and nearby that are completely open, but this colony seems to be all closed up. should i be worried? I have other zoas close by but they have been placed together like that for about 4 months now and have been perfectly fine. i hdont want to start loosing all of my colonies. Any help will be greatly appreciated thanks
