Please help Identify this Algae

This stuff has pretty much stuck to this one rock and was always dark in color.
Took the rock out of the tank today for a few minutes while cleaning, put it back in, now there's this bright color.
Thanks!

Checked it out, you nailed it thanks! Sounds like good stuff to have, if anyone would like a clipping or two let me know I'll give you some.

yea good stuff, got some in my sump. gotta be careful it doesn't get in dt unless you want it in there. somewhat of a slow grower though.

Looks like dictyota algae to me, which is very invasive and not much eats it except rabbitfish. I'd get rid of it while you can if it's isolated. It's a PITA to get rid of one it's established.

We're pretty sure it's Flame algae after looking at a bunch of pictures. Besides that we had added a green emerald crab recently that eats it like popcorn.
We found out the color changing like that is attributed to Astaxasthin a chemical compound from the Terpenes class. Pretty cool stuff.
