What kind of algae is this?

[brians]

My live rock came from an established tank. I was wondering what kind of algae these were and if they are good or bad.
This green one is soft and long...

And this purple one is short and coarse...

Thanks in advance!

First one looks like hair algea.
Second one could be a problem, is it really course?
Like stiff toothbrush bristles? Won't even scrap off with your thumb nail?

It's not really stiff. It is really hard to scrape off though. Here is a better picture...

Well, I did a little more research and found that this is Red Turf (Gelidium pusillium). Is this what everyone on here refers to as red hair algae? I guess I'm going to get a few Mexican Turbos and see if they'll eat it.
