Reefers i have an infestation of these worms found around my star polyps. Really fine transparent thread like.
I got a coco worm and this was on its shell.
i'm guessing the green things are sponges?

I agree, nothing too horrible here. If the critters in Image #1 and #2 are vermatid snails they will come out of a somewhat coiled shell attached to a rock of other hard surface and cast a "web" when you feed or otherwise disturb the water column. They are casting the web to catch food particles in the water. I personally don't like them much and will break them off with a dental pick when I can. Others don't mind them.
