I'm pretty sure that I can frag this the same way as regular shrooms (cutting in pie pieces) but just wanted to check here first before i perform the surgery. he started at a 2 inch diameter and is now taking up and entire side of my tank at 12+ inches so i would like to frag him. thanks in advance. you can see him on the home page here. he's the one on the right side of the tank and he's not even fully opened lol. http://www.captivereefing.com/showthread.php?t=4939
