I never had them kill any of my zoas. I do place them lover in my gardens as they shade smaller species.Same. I have done it to move them off the rubble I got them on but since then I don’t even wanna brush against those dudes just to be safe. Also if you haven’t had the lovely experience of it yet, everything they touch withers and dies. They sting the crap outta my other zoa so they are soloing it on a rock.
