The mushrooms can take a long time or be quick, at least in my tanks. I have a mushroom that keeps moving and leaves baby mushrooms in his path.
I find zooas to grow really quick usually. Within a couple weeks you should have some new polyps pushing out and within a couple months they should completely overtake the frag plug or rock they are on.

I have a mix of many different saltwater fish amongst my tanks, but I love my Tangs most of all.
