What is this thing???

Any ideas what this thing is? Its been moving slowly for the past few weeks, started out along the base of the coral and I missed it - its currently on a mushroom finger leather coral... Survived a coral dip...
Is it harmful?
what do I do with it?

That looks like colonial tunicates. They are harmless filter feeders.

Thank you! How interesting! Google showed a lot of different types but that’s exactly what it is! Glad it’s not harmful!
