Is it possible to frag a bubble coral? I've never heard of anyone doing
this, so I'm not to sure. I have a nice octobubble that is much to large for
my tank so I have it in my sump until I find a new home for it. Is it
possible for me to frag a small piece of it so I can keep some of it?

Thanks

I have read of people fragging bubble coral. The procedure involves tools like hammer and chisel. Why not try to find the coral a new, larger home and start fresh with a smaller bubble coral?

I have a hacksaw, fitted with a tile cutter blade. With this, I cut through from the bottom, to as close to the flesh as possible without touching the flesh. For the next step it's best to have two sets of hands. With one person holding the coral, the second can tap a wedge of choice into the cut, forcing a complete fracture. You must have the two pieces held securely so that tearing doesn't happen. After the complete fracture, prop the two pieces together in the tank so you can slowly move them apart over a period of time. I like to move them marginally apart about once a week. You will get a feel for when you can separate them a little more as time goes on. Eventually, the two pieces separate. I haven't done enough to get a handle on how long the separation takes on average as the four I have done have all taken different times. There are probably too many variables to consider to give an accurate time, like the amount of flesh at the fracture, to even the tank conditions involved.
