Hammer growth question

[acrouse]

When a branching hammer grows, does the original base increase in size? Or do they just produce more heads?

I am wondering because the base of my hammer is tightly wedged in a hole in my live rock and I do not believe there is expansion room. So if the bases expand I need to move it.

Thanks for any information.
