Looks like the start of green hair algae and coralline.

Is hair algee good or bad?

Green hair algae has been called many things, good won't be one of the top ten. I suggest you just do a search for GHA on this site and you will get plenty of information. I tried to do a quick search to give you some links but my internet seems to be on holidays today...

Buy some Trochus snails or some hermits like hair algae. My Tail Spot Blenny chows down on any in my tank.
