Some fragging help please! :D

[Cichlidius]

I have two corals that I want to maybe frag. I have fragged other kinds of coral in the past like capnella, shrooms and sarcophyton. I want to frag a Rhodactus (very large, maybe 6"-7" across when fully expanded) and a donut coral (Scolymia Coral). (I am not considering fragging it now I just want to learn a little bit more about it) No pic of the rhodactus.

This is not my coral (I wish it was ) but a representation of my species of donut coral:

if it were me I'd hang it upside down in the water gently so it dont retract and lop it off, and hope that it comes back where it was lopped off

The donut or the Rhodactus?
