If it were a branching hammer there would be plenty of room for it to fill in, I can't say with a wall hammer though, they have a completely different growth pattern. I have a branching hammer that is getting too large for my 20g, last count if I remember correctly is 38 heads. It's turning into a nice large ball/sphere, hopefully I don't need to frag it since it's real close to one of my duncans and it's gotten rather aggressive lately with sweepers etc.
