GSP overgrowth

[kenter16]

I was just wondering how to control the growth of my GSP... It is taking over my tank, quite literally. When i purchased a frag of it last christmas it was about 4" by 4", now it takes up almost half of my ~95 lbs of live rock. I used to have a ton of cracks and crevasses where i would put other frags there. It grew right over a couple frags of zoas. I was hoping there was a fish or invertebrate out there that will snack on it. Not that I want it gone, just if I keep letting it grow uninhibited it will cover everything. I was thinking of buying a couple corals that pack a good punch, like a frogspawn and setting up a perimeter. Is that a good idea? Any help would be appreciated. Thanks.
