Fragging

[Jus_sum_guy]

First photo....

There are 2 stalks on the little Rock with 2 heads on each stalk. I would like to take it off the little Rock and plug it into one the of many holes in my live rock.
Can I just cut at the bottom of the stalk, closest to the rock, so both heads are still attached?
Will sideways cutters work? It's all I have.

2nd photo....

Can I do the same to the 4 heads of toadstools?
Although with this one it may have to be 4 individual frags...

Thanks for any help. This forum has been awesome in getting me started so far!
