Looks like coralline algae to me. Comes in many different colors such as red green and purple.

I'm seeing reds greens blues yellows purples and whites in my tank and I love it , everyday you don't know what you'll find , Also I added a set of LEDS and between the Coraline and the LEDS at night the rock comes to life with color especially when the other lights are off , and getting to see all the critters come out from hiding

Not at all. Lots of people buy products that promote the growth of coralline algae, I just prefer to let it grow on its own. If it starts creeping up your glass, you'll want to scrape it off, unless you don't mind not seeing inside your aquarium....
