There are white hairs/spikes (like urchin’s) growing on the stem of my elegance coral frag.

May be little tube worms. Ive seen these on mainly hammer coral. Harmless and you can brush them off with a firm toothbrush

I have tube worms and these don’t look like tone worms. These look like urchin hairs.

I’ve got these on a few frags, I’ve dipped and brushed off and they just come back. Seen some spreading I believe. Anyone? Some suggested hydroids but I cant find a species pic to match. I’ve heard of predators that may eat them but I’m looking for a way to take frag out of tank and kill it.
-Also eliminating Ball Anemones!

I have the same thing on my hammer and it is not doing to well right now. When I brought him home I dipped him and tried scraping th off but they were attached, now they are sticking straight up and I can brush them off easily, but I don’t want them to contaminate my tank. Anyone have any updates?
