Algae ID

This algae was barely there 1 1/2 weeks ago. It came on my live shipped rocks from gulf of Mexico. Its growing pretty fast and is starting to make me nervous that it could get out of control. It is in several places on the rocks.

Anyone know what it is and what will eat it?

Hair algae and possible caulerpa or mat algae which may have been on live rock.
Pull what you can by hand and reduce white light intensity. Assure also that your phosphate and nitrate are Not elevated.

Here is a better picture of a different clump. Do you still think it's hair algae? It has a center stem with feathery leaves.

I think it might be verticillata caulerpa after searching through pictures.

This is a 10 gallon tank, so no tangs. And my 3 blue legs are not touching it.
