maybe I missed it (entirely possible!) but I've not yet seen proof of Stichodactyla gigantea successfully propped by knife.I have seen reports of gigantias being artificially split with a sharp blade (not that I am recommending it) like an Entacmaea and surviving. I don't know how reliable those sources are though, or if that implies the potential to do so in nature, or if it maintains the genes to allow it to recover from splitting but not for starting to split, or really what it means. Just throwin it out there.
