Are there Zoanthids that are impossible to frag?

[Thricelll]

Most of the Zoanthids colony I've come across are relatively easy to frag. I simly take a razor blade and cut the mat. My question is how do you frag Zoas that have basically very little stem and a very thin mat? When I try to slice under I end up cutting the head.

I try to cut the mat like you even for long Zoa, Most of them die on me, Can you tell me what did I do wrong?

you have to pry off a thin piece of algae under the polyp. i have polyps that i frag this way. just pry under them gently and they should pop off.
