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:

I've effectively snipped off portions of Rhodactus to make frags. Never tried a Scolymia, but it being a large single polyp, I personally wouldn't advise it. I've seen people make frags from Cataphyllia and Euphyllia, but I've also seen entire colonies die from protozoan or bacterial infection after being cut, not to mention a lot of the snippets don't sucessfuly lay down it's own stony base before they dissolve away or disappear in the current.

So it is pretty much going to have to reproduce on its own eh, that's cool though, I wasn't planning on hacking it up yet anyway.

With the Rhodactus did you get any piece of the mouth or base? (mine doesn't really have a base as such) Mine is the size of a dinner plate it's time to frag!!!!

Rhodactus gets huge! 8) The best success I've had is to cut long pieces perpendicular to the mouth (like cutting a pie). Cutting it this way results in a deformed looking Rhodactus, but it has the highest probability of success. Trimming the edges usually resulted in mushrooms strips that melted away

Once in a while, my Cynaria (much like Scolymia) would drop off little buds. But I personally did not dare to cut into its flesh; too big a risk for such little gain IMO.
