I have a Physogyra bubble coral that is getting WAY to big. It has a bud in the back, and is hitting the rock to its right, and is about to hit the frogspawn to its left, any safe ways to frag these guys? Should I first try to make more space for him before ***ging? It has around 7-8 mouths and is 8" across. I will get some pics after it is done being pissed off.
