Small trochus like snail ID

[kjkszpj9]

This very small snail like 0.5cm big has same tentacles that stick out underneath like a trochus but it is likely not growing bigger cause they are laying eggs constantly. Any idea what the name of these are?

At my workplace where i got them, there are hundreds of these small snails in the coral aquarium tank in the sump and display tank.

Ahhh, thank you. I completly forgot about those snails.

So they are some other kind of collonista snail even though their shell spirals upward like a pyramid compared to other collonista that have a circular shell?

If you have trochus, could just be baby trochus

No i can tell the difference from this one and another small trochus in my tank and they are very different.

Neither have I.

Unfortunately, I don't know for sure what kind of snail this is. I would guess it's a Periwinkle (family Littorinidae) of some variety, but I could definitely be wrong on that.
