Darren, that's awesome. I never cared much for NGs until I saw a colony that size.
How many polyps did you start with and how long did it take to grow?
casey
Casey it actually started with 1 polyp like you see on the plug in the pic. I had them mid way in the tank (under 2 150W MH) and they grew new polyps but they were spread out. I moved them down a few months ago to the bottom and they have really filled in. The colony is probably 9 months old.
