Questions about Chalice

[WarDog]

So I am starting to make a wish list of corals I want for my new tank. I'm really getting excited about Chalice but I am not finding a lot of online information about them, primarily scientific.

My main question has to do with their size. I've only ever seen 1" frags on a plug. How large will a Chalice get? Will it spread out or spiral up like a Monti? Will it climb the vertical or just stop?

If anyone has pics of colonies (not just a macro of one mouth) I'd really appreciate it if you could post them here! Thanks!
