In general, photosynthetic gorgs are the only ones that are reasonably easy to keep. Good flow, good light & they're happy. They are mostly tan or yellowish in colour though.
The more colourful gorgs like blueberry and the really nice red or purple ones are non-photosynthetic and need to get some sort of coral food. A lot more maintenance & time and much lower success cause you almost have to pollute your tank and overfeed in order to keep some of them happy.
I've had some of my photosynthetic gorgs for a year or three and some I got from my buddy Daniel that he had for a number of years too.
Mostly tans and yellowish photo. gorgs though.
