It's like inception, you're quoting yourself.
I read you can just cut off the heads to frag? Said will take longer to regrow.
So just pry them up off the rock, or get a knife and try getting under them?
You are asking for some real trouble should you cut the head off, your going to cut the guts if you do that and that's were all the bad stuff is, and your more than likely to kill it, think about this..cut off my arm,, I'll probably live, cut me in half at the waist, um ya!! Not gonna live!!, same deal with the Zoas ,, your best bet is to get them to be as mad as possible,why? As this will get the most water out of them making it easier to pull off of the rock also making them more rip resistant while pulling away, be careful!!!!
