How to grow out a large candy cane or hammer colony?

[Schreiber]

Both of these corals have been growing at a crazy rate in my new tank. They're getting to the point they've "filled in" their readily available area. Will these sort of corals keep growing onto the rocks themselves like zoas will? I've always assumed they don't. But how do people get giant colonies like this?

My coral photos for comparison, to show the area I'm working with:

Theyll keep growing from the central stalk of the skeleton so if they're running out of room it may be time to consider fragging. Its a good problem to have.

I had a candy cane colony that formed around the rocks. I'd stuck a single head into a hold in my rockwork and it had to grow out of the hole.

Did someone say candy cane?? This is about 3 years of growth, started as a 2 polyp frag. Now I can't count the polyps!

My candy canes are doing the same thing. They keep growing heads but no new skeleton. Pics are when I got them versus now. Been about 5 months of growth.

Technically they are, or there would be no place for the polyp. But yeah, it takes a while.

Candy canes will be my next add love the variety or colors they add to tank
