I have a zoa colony of gorilla nipples that is dying off and I can't figure out why. I've dipped in coral Rx and lugols with no improvement. I've already lost another colony entirely. What I need help with is fragging what's left of this colony to save the healthy polyps. I'm a newcomer to coral (but an aquarist for years) and am afraid to frag zoas because of the palytoxins and also just don't know how. Would anyone be willing to help me? I'd be happy to share some of the healthy polyps as a thanks! I live close to the Science museum and could meet there if convenient. I would deeply appreciate any help or advice on what to do to save this colony!!
