Don't worry ! Give it time and it will be all over the rest of your tank. Unless something eats it. Or you remove it.

It can be a hit-or-miss with trying to find something to eat it, but for me, my tangs devour the stuff. I always bring in random macro algaes on corals and my yellow and purple tangs go to town on it. You probably obtain the hair algae as a hitchhiker on that coral and didn't notice it because it had not taken over yet. A lot of people also use sea hares for larger infestations. I wouldn't recommend one for you though if it's isolated to that one coral.

To be honest, if it were me I would just frag that coral and throw away the major parts that have the hair algae on it. That looks like a green birdsnest which actually grows quite easily, especially from frags so you could make probably a dozen frags out of that mini colony and throw away the parts that have hair algae on them.
