Mystery critter

[Ishaithecoralguy]

Hey everybody i have hundreds of these in my sand and rocks, they each have two pf those little white feelers and each is about an inch. i am wondering what kind of worm they are. Also what kind of snails are these, they breed like rabbits. I also have these wierd polyp/ feather duster things that form colonies, they are the brown under my frogspawn, they get much bugger and form small brown calcified skeletons, any idea what they are?
