With all due respect to Justin/Fin & Feather...
I don't think we need to wait until Spring to talk about care and feeding of Goniopora... or even fragging for that matter

. As Greg and Chuck have mentioned, they are being kept successfully by people right here in our club.
The red variety with purple/blue centers - at least the ones I've seen, and the one I own - are typically G. planulata. I have not fragged my frags (yet)... so I'm on second generation propogation, though I've had my parent colony for about 4.5 years.
There is another reddish/pink variety of Goniopora more readily available at LFSs. Thinner, more transparent polyps and no bright blue/purple centers. I believe that one is G. stuchburyi... not as colorful, and seems to thrive in less light than planulata. I had one... chopped it several times with no problems... then sold the chunks because the color didn't come close to my planulata.
Food - As Andy suggests... Tang crap. Periodic doses of phyto, the smallest golden pearls, even a baster blast of nastiness from the bottom of a protein skimmer (if you dare to go there). Nothing so expensive as oyster eggs necessary in my experience.
Lighting - Mine is on the sand, under 250 Metal halides... so I'd say 'good' lighting, without suggesting anything up on the rocks toward the 'strong' lighting end of things.
Flow - Of great importance, in my opinion... alternating and not too harsh.
