Clove polyp propagation

[Bouldereefer]

I purchased some fireworks clove polyps at a show about 2 months ago. The original polyps have moved, no big deal. They have formed a large mat of “runners/roots”. Will the eventually turn into polyps. They are getting somewhat out of control.
I have attempted to add a picture

It’s hard to tell from the picture, but that almost looks like a sponge to me. Do you have a picture of the actual polyps?

I see like 4 cloves and the other white stringy strands do look like sponges.
