Red threads coming from a central point

[MattPLaw]

Hello All!
I have attempted to take a few pictures of some sort of Algae? That I have growing in my sand. It looks red under blue reef light. It has threads up to 2ish inches long all comming from a central point. The threads are very fine and blow around constantly. Does anyone know what this is?
I just went through a course of Reef Flux Fluconazole that took care of my bryopsis, but this stuff has not changed.

Please let me know if anyone recognizes this. No one seems to eat it.

I think you have spaghetti worms. They eat detritus and dont harm anything that I know of.

I will look into that, thanks!
