Soft tissue shed from pectinia thriving?

[Rebbel]

I had a space invader pectinia for a couple weeks that unfortunately died due to bad flow placement. It was shedding chunks of its skin before death that seemed to either be captured in my filtration or died/decayed.

However, one piece of skin seems to have survived after weeks of the mother colony being removed and is otherwise thriving. Its neutrally boyant so any disturbance will cause it to move, but otherwise seems to be happy.

Has anyone seen this propogation/budding behavior in pectinias? There isn't another coral in the tank that would have this particular coloration so I don' think its shed from a current inhabitant.

It will regrow from that little frag of tissue.
