Did you guys all start off with just a small frag of them and let them grow?  Or did you buy large colonies of them?
How long does it take for a 15 polup frag to actually cover an entire rock like a 10x10" section?
Just converted my FOWLR to a beginner reef and bought a lot of zoas but they are just on frag plugs.  10 scattered frag plugs of zoas look awfully small in a 180 DT.
Thanks!!!!
