Is this an algae? Need help identifying

It’s been growing on this rock my freak hair is on. Seems like it doesn’t bother any corals but would like it gone before it spreads anymore. At night the flower polyps retract

The first thing that comes to mind is cyanobacteria

The feathery look would make me want to agree. But Kj will know for sure

Are you more worried about the red slim or the white tube sponge sticking out of your polyps they are harmless.

It’s not slim look at the picture closer. More like a feather/flower

It not green. The color of it in the picture is the natural color. It doesn’t harm my corals like I said. It hitchhiked and has been there for like a year n a half. Just trying to figure out what the heck it is!! I know for a fact it’s not cyano. I understand fully what cyano is
