Ben - I haven't seen anything in your photos that would worry me. I am still having a hard time trying to determine what white dots you are talking about, though. I love looking and learning about all the small things in tanks.....and there are so many varieties of each.
Regarding vermetid snails. These are snails that make little tubes, and from the tube they put out a mucus netting, which resembles spider web strands. They catch particulates in the mucus and real it in to eat. Here are a couple of articles: Worms that ain't.....Vermetid Snails in Marine Aquaria, and Snails That Worm Their Way Into Tanks.
Terebellid polychaetes (aka spaghetti worms), which is what I see in the photo, use long tentacles and sweep them across the surfaces to capture food. Here are some articles: Spaghetti and Hair Worms....What's in a Name?, Reefkeepers Guide to Invertebrate Zoology - scroll down to Terebellidae (in the same section as Spirorbidae), Spaghetti Worms Utilize Tentacles in Amazing Ways
Hope this clears up some confusion.
