White nubs growing out of Substrate.

These white nubs started growing out of the substrate a couple days ago.
They are close to the base of a Shaving brush plant and I think they might be off shoots of new plants.
They have little bumps at the top and what look like roots going into the sand.
The larger one is starting to get some color. If these are Shaving brush plants, Great,if not should I remove them?
I've used a filter on one pic to better show the texture.

I think you may be right. Look at the plant in this video, it has bigger runners but the tops of them look just like yours.

Thanks, I actually watched that yesterday while trying to research this.
