ID: Single red bubble polyp things? Help!

[Payton Engelen]

I have noticed small colonies or single dark red/maroon colored coral(I believe) growing on my live rock. They are starting to spread a bit and I have no idea what they are. They are soft and look like a single bubble on a stem? Some of them are by themselves and some in small colonies of 4-5. I haven't been able to find any information about them. Anyone have any idea what it is? I will post a picture shortly.
