Does this look like hair algae?

[Ula Hula]

I put some chaeto algae that was purchased from this site into my newish tank. After a while, though, I saw that a different type was growing. It's finer, less wiry, and tends to anchor to surfaces, unlike the free-floating chaeto.

Is this hair algae on the left? (I've contrasted it with the chaeto on the right.) If so, I'll try to remove it. Thanks.

Yes, that appears to be some kind of hair algae.
