Is this Caulerpa Taxifolia?

I rearanged the rocks in my nano tank, and it just appeared almost a year after setting it up. Nothing else was added.
As if it was dormant and just sprouted.

First we're gonna need to see a full tank shot, and then you can have your answer.

Its either Taxifolia , or Mexicana .

Seriously though, we do need to see a FTS.

Or perhaps: sertularioides??
