I have 4 snails living with my 5 axolotls currently but one snail is concerning but I don't know where to post this at

All snails are nitrate(or however u say it) snails, currently they all don't have pointy shells but there's this one snail I have that came to me looking like this- Does anyone know anything about the type of snail and what I can do? It arrived from a petstore looking like this, he's doing much better currently and there's no issues yet but I tend to worry
