Have a picture? That might help us identify it a little better...

Google vermetid, they are a sessile inverts that "fishes" for its food by putting out lines and reeling them in when they grab something. Harmless, but can be annoying.

I agree, it could be a vermetid snail. They can be annoying, and their 'web' will annoy most corals. I nearly lost a hammer until I found the snail and killed it.

Could be sponge. Without a pic there's no way to give you a positive ID.
