I have a gorgonian frag--about 1.5"--that I got from ??? a year ago February. It is tan with darker polyps. I had a type of the same about 8+ years ago. It did well then, and this one has, well, done fine. In a year and a half it has not grown much (if I can recall), but it is healthy and shows polyps during light/feeding and retracts at other times. Hasn't built any base or spread or extended in length, but it is hanging just fine.
I also got a gonioppra from Aaron in a trade over a year ago. It had done well for him, seemed healthy when I got it, and extended itself. I placed it too close to my carpet anemone, and it got stung a little bit on one edge. Nothing major, and nothing that would harm any other "regular" coral, but the 1/8" stung area around its base caused it to recede, never open fully again, and wither away in about a week or so.
That's what I've got from experience. Hope it helps.
