How do I frag a sun coral?

[GrimReefer]

the sun coral is doing great. every polyp is opening before the lights go off (just like I trained her) . i've also discovered that it's a lot easier to get food to it after the lights are actually off. my fish have insatiable appetites for brine shrimp. anyways, my experience with this makes me want to frag a whole colony into 4 or 5 pieces and see how fast they grow.
