The color on the pic is reasonably accurate.
I have a 125g tank (60" long), with a sump/refuge with a Coralife Skimmer. I have 4 x 110 watt VHO lighting, with two actinic and two 10K bulbs. Flow is a Koralia 3 and a Koralia 4, along with flow from the sump. The coral is about 18" below the light in a medium flow area.
As for parameters, they're about average, with nitrates running about 2ppm, calc. at 420, alk. has been a little low, but I try to keep it at at least 3.5m/eq. and salinity is at 1.025. Temps are steady between 79 and 80F.
I don't usually directly feed it, but I do feed the tank mysis twice a day (most of which the fish get) some H2O Life coral food (frozen food, a mix of veg and cyclopeeze, mostly cyclops-sized pieces) about once a week, and some homemade food mix once a week (ground up seafood, with garlic, Selcon, etc.).
I've seen the coral capture whole mysis, but haven't stayed to watch if it eats the whole thing. It definitely does capture the frozen coral food.
I haven't really noticed that it suffers if it doesn't eat or if it does better when it does. I feed it anyway, and it seems to be doing fine. To be honest, it doesn't seem to be a very picky coral, and my tank is less than a year old (as is my saltwater experience), so I'd have to say it's fairly forgiving.
