Snails?

[Justin0329]

On my back glass I have several (50?) Small white snail looking things. They don't move but they weren't there a few days ago. I'm wondering if my large snail (unknown breed) laid eggs or something. Any ideas or has anyone seen anything like this in their tank?

Do they look like this?

Its hard to tell because your picture is blurred. However, they are white like that and they have kinda a spiral shape like that. They are also hard. I tried removing one to look closer and it seemed stuck pretty well.

spirorbid worms. Common in new tanks to see an explosion of these. Harmless filter feeders.
