Please Help Id Snails! Box/Pyramid?

Found some of these in my tank. Im scared the round ones are box snails and the long pointy ones are pyramid snails. Can the small pointy ones be baby ceriths? I have around 50 adults. How do you tell the difference between baby ceriths and pyramid snail?

Also what kind of snails are the round ones with markings?

 

I agree

 

Thanks, the round ones are for sure Collonista.

Are you sure the other ones are not baby ceriths? They look like baby ceriths just more white. I haven't found any on other snails. How can you tell if they are ceriths or pyramidellid?

 

When cerith snail eggs hatch, they go through a planktonic stage. What our filtration doesn't pick off will be picked off by our live filtration (corals, featherdusters, etc.) That's why people don't see baby ceriths.
