Galaxy coral growth
 

I just got a galaxy coral frag and was wondering about how it will grow. Will it grow over the frag disc and spread on to any rock I glue the disc to or should I cut away as much of the frag disc as I can and then attach the frag to a piece of live rock?

Galaxea will grow onto a rock. I have some on my live rock from leaving a frag laying on it, and then removing the frag, but it has encrusted onto the live rock. It grows really fast too!
