Green Star Polyp and nano Tank

So I was thinking of glueing a piece of my GSP coral frag onto the back wall of my biocube. I know I have seen people do it and I really like how it looks. I was wondering if anyone knows of any drawbacks or anything of doing it? I have the small frag in the tank now and just cant decide if I want to glue it to the back wall or not.



I dont want to do it and regret it later. I know it grows pretty fast and spread out.
