Can anyone help me identify these snails?

[Theafishtank]

I ordered a bunch of fish and invertebrates to restock my tank from liveaquaria.com a few months ago. Very quickly I started noticing these little snails pop up, I'm pretty sure that they came in on my Japanese trap door snails.They're multiplying really quickly so I'm sure that there's some sort of pest snail, but I don't mind them, Cause my fish eat them. Younger ones have a slightly translucent shell, and some of them are almost purple. They all have stripes running down the length of their shell. The bigger ones are more dark, but you can still kind of see their stripes. They move really slow and they almost never put their little face out of their shell. Their body is Brown with a hint of green. The little turret that they have doesn't form until they get bigger, they're almost completely round with they're smaller with just a tiny tip at the end. I've been taking lots of pictures of them, so here are some of the best ones. I've posted them on social media, I've used Google image search, I've used a couple different identification apps nothing has worked.
Thanks for the help I'm super stumped on these guys

Could it be viviparus viviparus?

Or maybe a hybrid of the two
viviparus viviparus and viviparus malleattus?

I think you might be right! Thank you!

See if some snail babies look like one proposed parent and some of the other variety. Or all blended to look like each other. I'm curious!
