Zoa growth?

[V4Vendetta]

how fast do these grow? I'm trying to get couple frags of zoa for the first time and was wondering how much space i should or need to leave for the zoa to grow? Does it just grow over other corals when the two different corals intersect with each other?

Once the frag has settled usually for me lower light areas I got 1 polyp almost per day after about a month of being in the tank, but then again I had a a really dirty tank cause it was all polyps and LPS...

Once they're in the right spot they spill. It's the neatest thing. Don't play with them too much by moving them around, it'll inhibit growth.
