I have your typical 'Christmas' Favia, green and red, and I swear it hasnt grown a bit in 8 months. It is in lower light near the bottom of the tank. Colors are great, but man, are tehy really that slow?
It sits on the sand bed of my 90 with 6 t5's 4 overdriven, but most of the growth happened in my old tank, on the sand bed with a stock nova extreme pro fixture.
I think I have fed it like 4 times. I just do it when I am really bored and not drinking at 1am...I'll get a pic up.
Favias grow quickley for me too. I have a War favia that has 14 new heads. I bought it 2 months ago. My other favias grow quick too. I have most of them a little more than half way up under a 400w XM 20k and two superactinic VHO's with one 50/50 vho. I feed every other night with vitamin enriched brine and have lots of flow.
I don't really have a new tank thread, my tank was cheapley put together at first. Over the 2 years of having my 65g i have upgraded almost everything. I have a 24" tank that will be here in a couple of weeks, I'll have a tank thread when that gets in.
Oh and the 400w halide was the best thing i have ever done. My SPS are getting color back and growing. I have it about 14" above the water and it lights up my entire 36" tank. The Luminmax pendant does it's job.
Here are some pics of my favias.

And my war coral that gas grown many new heads in just a couple months
you can see where it is buldged out. It started 6 months ago with 1 full circle around the buldge. Now it has spread out all over that rock. I am trying to get it to spread to the rock behind it and below it now...
