identification

Hello everyone I’ve recently noticed some tiny snails wandering around my tank. I don’t believe they are causing any harm however I would like to be sure. I was wondering if anyone could help ID these little guys for me? I do have a pair of trochus snails wandering the tank and I’m not sure if...

Anyone know what these are called?

I've been unable to locate images or information online... Any thoughts?...
