Not Entirely true since everybody handles things differently. I'd gotten palytoxin poisoning multiple times just from having my hand/ arm in my aquarium. Afterwards I would get extremely tired, lightheaded, nauseous and occasionally dizzy, as well as a metallic taste in my mouth. I never had any cuts etc on my arms or hands. I didn't have to touch the zoas or palys, just having my arm in the tank in general would do it. Absolutely 100% No fun whatsoever lol. I spoke with Julian sprung about it years ago at the Aquatic Experience in Chicago. He told me about his experience with it as well and that their periodic mucus secretions can be more than enough to affect different people. He also told me how if out of water for some time they can vaporize their toxins. I sold all of my Palys and Zoas a couple weeks later, at most, and haven't had any of those issues ever since. LOVE Palythoas and Zoanthids, I had incredible luck with growing them but my body doesn't like them so I don't keep them. It's amazing how differently things can affect people
