For better or worse, it's main value is to you. Treasure it. (It's beautiful!!!!)
"Weedy" corals like these naturally keep the market saturated, so at most you'll "sell" frags to just your local friends. I don't think I've managed to get more than $10 a frag, and bigger isn't usually better....folks want frag sized frags to start with. Grow more colors and keep it interesting for you.
IMO unless you are making this a specimen tank (and this coral makes an AWESOME specimen...seen sone real biggies) don't be afraid to wreck the colony and make it start over. Sounds horrible, and I was never very good at it, but it's real.... :) On the upside, I have saved some massive skeletons from corals I've had to remove for space reasons....they're still around and might become "live rock" someday.
