Tiny Snails Good or Bad?

[Mahawka]

Hey guys,

I found a bunch of tiny snails in my tank today. They are all stuck on the glass wall. They are so tiny I can't really take a picture of them. They are about 1 mm in size or smaller. Circular spiral shells. I can easily see 150+ of them. Some of them are super stuck to the glass

I have 2 Tubo snails in my tank. Is it possible that they spawned?


Does anyone have any thoughts on what these could be? Should I try to manually remove them before they spread? Or are these healthy snails that I should keep ?


Thanks
