I got it as a browned out mariculture colony from my LFS, was wondering if anyone knew what it was. It has super long polp extension. I have included pics of it in my (blue spectrum heavy) tank with and without a blue light filter. Pics on iPhone 13.
That’s what I originally thought, but the diameter of the offshoots is much larger than my other Millipora. Like almost as chunky as my humilis. It looks like a hybrid of the two?
