Someone should mention the probability of the polyps having toxins...
Be overly cautios when handling and or fragging Zoanthus or Palythoas. They have the ability to have palytoxin in the tissue. Once damaged, the natural tendency is to defend itself. The concept of propagation through fragging is not something the coral will understand.
Wear gloves and protective eyewear when fragging. Avoid allowing any tools used when cutting to be handled by anyone/thing. There are horror stories about the dangers of palytoxin all over the web.
