When I was in Upscale last, they had one - that was about a month or so ago. I wish I had the room. It was very nice looking. Also, WAVES had one about 4 or more months ago. But I think it is gone.
I have heard they are very difficult, but if I had the room and I found the right specimen I would give it a try. It does worry me that Steve ran out of room :>) I currently have several rose and green BTAs and a Haddoni carpet anemone. I find with good light, a good set up and proper feeding that these anemones are not hard to keep.
A gentleman on reef central kept one for a very long time, until a week or so ago when he had a full system crash. You would fine old posts by him if you search.
