Stomatella, or?

Noticed another thing in my sump today I had not seen before. These little (like pin head size) guys are all over the wall of the sump. I pulled out and took a photo. I think it's a stomatella, but they are so small hard to be sure. Difficult to get a good pic of the underside. All the Stoma pics I find they are bigger than their shell, so not sure.

Is it upside down? Looks like one. Do they have antenna when on the glass moving? Stomatellas are pretty quick moving as well

First pic is right side up, second is upside down. None of them were moving actually. Just sitting in one place. Saw no antenna or anything of the sort. Just the "shell"

Looking closer at first pic, I'm going to say limpet.

Cool. Thanks. Either way it's a good guy. Just thought I would get confirmation it's not evil
