Bumblebee snail babies!

[Sebastian the Lionfish]

I am about 80% sure my bumblebee snails are breeding, but cant say for sure. I just noticed a tiny little snail maybe a 1/8 inch shell with similar colorings to my bumblebees. Anyone have experience with this happening before? I heard its rather difficult to get them to breed. I just want to make sure it's a baby bumblebee and not some other kind of possibly bad hitchhiker I have just never noticed. Thanks!

After more research could it be a glowing marginella snail?
