Merletti is the kind that is branchy.
You frag this kind by just breaking them with coral snippers.
Wellsi is the kind that grows like a acan.
You frag this kind like you would a acan. Just take a dremel and cut deep slot underneath of it and use a screwdriver to snap it. Us a razor blade to cut the flesh.
Well I never cut too deep, I never let the blade touch the flesh. Like I said cut a slot under the rock it's on and use a screw driver and crack it. Then use a clean razor blade to cut the flesh if it is hanging on by its flesh. I think when you frag Blastos you need at least 1 head??? (Can someone confirm this?)
