Anthellia xenia. Has potential to spread but I personally like them

I would get those out if I could

Put the rock in a bucket of salt water

And brush them off with a wire brush

Wearing PPE

That's what I would do, if I didn't toss the rock into the yard

Looks like a type of xenia coral.

Is it harmful to other corals? Cause my mushrooms didn't kinda like it
