I have a Devils Finger that I have successfully fragged but I'm not sure about the others. Actually that's a lie. I didn't frag it, Dory my Tang fragged it for me and the bits grew on their own, so my involvement was very minimal.

Anyway point is it seems that if I want to frag Devil's Finger I just lop a bit off and glue it to a rock or leave it on a rock to attach itself.
The others I've got are :-
Torch Coral, I understand with this one I could break a head off at the base as each head is its own entity. Not planning to do this, just want to know how.

This Finger Leather. It's likely I have to do this one soon. Lop a bit off again?
I've got an encrusting leather too. It coats the top surface of some reef bone. This has spread to an adjacent rock on its own so should I put a bit of rock next to it then cut it away after it spreads?

Mushrooms: There are about 8 mushrooms on this rock but they don't seem keen on going anywhere else on their own. These are probably the most confusing to me.

Xenia. Not a clue?!

Old photo but more mushrooms of a different type and a little pussy? Not ready yet but I'd still like to know
Any hints tips and links gratefully received
