Fragging Green Birdsnest

[Enigma]

I have a green Birdsnest that I'd like to trim to make a little neater looking, and maybe thin out a little so more light reaches through the "branches." It is an "ORA Style" I think. It grows very nicely in my system. I don't remember when it was given to me (maybe just over two months ago?), but it has trippled in size while I've had it. The lower "branches" are quite brown, while the upper ones are a beautiful vibrant greet.

I have frag plugs. I have frag glue and epoxy putty. I have a little pair of side cutters that I actually use for flytying, but they're the most appropriate cutting tool that I can find in the house.

What's the best way to go about this?
