I've seen one at my LFS that's at least 15" or 16", though I haven't personally seen them larger than that. I can't say how long it would take to get to that size, it would really depend on a lot of factors (feeding schedule, other fish, etc). I was thinking of getting one for my 180, my LFS sells them around 2-4 inch for a good price, but the 18" thing has me thinking about alternatives.... of course I may end up going with one, I know a few people with huge tanks (owner of my company has something around 500g, from what I've heard) so if it really gets that big, I do have somewhere for it to go.
