what's this on my aquarium glass?

Hello, I was taking pictures of a sick clown when I noticed these small white things (snails maybe?) on my glass and even smaller moving "slug like" in appearance, yet fast moving creatures(dangerous??). What could they be? This picture makes my aquarium seem super dirty cuz of the macro... :uhoh2:

Good to know. I'm used to seeing them much bigger, I noticed these by chance. I'm assuming the other white things are snails since they have the sort of spiral shape common in those shells. I guess I'll have to wait and see till they grow.
Thanks for your response!

The spiral things are spirorbid worms. Harmless filter feeders.

Ah nice, I have those spiral things all over my biocube, always wondered what they were.
