DFS Pink Panther Grafting

[coral reeftank]

Hello Everyone, After about 3 years with my small frag of DFS Pink Panther that I had acquired from Adam at Battlecorals, I noticed something strange tonight while I was observing my tank.
I then got a closer view of it and saw that it had a several green streaks in the middle of my frag.
Has anyone noticed this occurring on their Pink Panthers, or is this a graft that occurred in my system?
What do you guys think?
