Baby snail?

Are turbo snails known for laying eggs in tanks?
I had a PVC house for a snowflake eel that I had a while back. I returned the eel a while ago and just go around to taking the pipe out of the tank tonight. When I got it out there was what looks like a snail stuck to it. Its about 3/4 of and inch long by 1/4 of an inch wide. It looks just like a snail except it could roll its shell up in a ball. I didn't add anything like that nor did he come in as a hitchhiker. Anyone know what it is?
