I got this as a boring purple stag from someone getting out of the hobby.  After a couple years, one branch developed green polyps, making this absolutely pop.  There's absolutely nothing like this out there from any vendor or hobbyist as far as I know.

I fragged the branch, and the polyps stayed green.  I have now distributed this to a couple other local hobbyists and can confirm that the color sticks under other lighting conditions and water chemistries.  This is just a real stunner of a coral!

You will get a 3" fresh cut frag with at least a couple small branches on it.
