How do I frag it?

[Viggen]

I purchased something similar to Xenia & I can't remember what it's called.  It's growing/spreading & I was wondering how I cut it apart.  Do I just pull the rock out of the tank & cut it? 

The stuff (possibly anthelia) is on a ceramic piece & I was thinking of putting that back into my main tank.  Then frag a small piece that't attatched to the rock it's sitting on & leave that in the clown tank. 

Didn't know if I just cut it with a knife & if I should remove it or should I keep the rock in the tank.

thanks

As long as it is spreading.  You could do what a friend of mine did.  He would just put some plugs or rubble around the xenia or anthelia and it would spread to those fairly quickly.

its presently on a rock & has spread to that.  Will it seperate itself or do I need to cut it to seperate the main piece on the tile thingy from the rock

Just pull it out of the tank and cut it..
