They are absolutely NOT hard to propogate... Mine would get so large that it would slowly fall over, and the foot would adhere, so the foot became longer. You could slice it a few times, and new heads would form. I finally sold it when I broke down my 18 gallon, and it died in the new tank. I originally got mine from Chris Little (Chrisaggie). I loved that coral. If it weren't for my theme of my new tank, I'd be looking for another piece.
