Looks like a stinging colonial Hydroid.

I would remove it mate.

Yep, looks like hydroids.

Generally considered to be a pest since they can be quite aggressive towards other corals. I have something similar in a few areas, been there for years and haven't spread so I've let them be. From what I've read they can be tough to get rid of, best solution seems to be to remove the rock and use a scraper and blow torch.

If it is a Hydroid ,and it looks like one they can spread and become quite a problem ,not worth the risk m8 .Have seen these in a orange colour ,if the same they will spread and can live on the side of an sps and sting it spreading ito the coral as they go :) .
