green toadstool

So I’ve been searching for a frag of a very long polyp green toadstool but haven’t had much luck outside of finding bigger extremely expensive ones on eBay. I like smaller frags over colonies bc I like watching my coral grow with my tank. Does anyone know of a good reliable place to find this...

Toadstool is roughly 12" across when open. It shed it's skin and has sense been completely bent over with it's head all the way in the sand bed. All other coral is completely fine including clones of itself. Just changed the carbon after it shed. But it has been doing this for over a week now...
