I think its the same that I have ~ A. Caroliniana. Mine is a metallic yellow/green.
Its not the fastest grower but not super slow either. PE only at night, and the polyps are very thin and white.
I had some tips that were white I think from shipping to my LFS and they grew back over pretty quickly. Id bet that if you could get that algae off without snipping the tips, it might grow back in those areas. But snip if you have to.
Now that I look at this picture it has grown a decent amount since I got it, but I dont remember exactly when that was
few months or so, maybe early summer time. This was under the old bulbs, 10k Aqualine ABs.
