A collectors item that we've been Aquacultring for a longtime.  Trimming it is a good idea because sometimes you can have more green or more red as it grows.  We've been trying to do frags with having both colors in the frag so you can have a cool growth.  More like a splashing effect.  When we see one of the colors taking more growth, we will trim it.
