Thanks guys. Yeah I'm really surprised it hadn't sold by the time I saw it. It did have a more plain look to it at the store, it just looked like it had a hint of blue. When I got it home on Monday I was amazed to see it open like that after 30 minutes in the tank. Usually corals sulk on me for a few days. I hope this is a good sign for longevity.
Here are some recent pics of the others.

I didn't get the colour quite right. The flesh is a delicate purple that doesn't show up well in pictures.
I also have a few others but no pics online yet. I'll try to change that tonight (need an excuse to exercise the camera anyhow).
