Baby Astrea snails in refugium?

[Salty87]

Can someone confirm that these are indeed astrea snail babies ? I had dropped a bunch in my refugium and have nothing else in there. Pardon the dirty glass, I have included a shot of an adult to their right as well. They are of varied sizes. I have had them spawn in the water column multiple times but never noticed any babies till now and from what I read is not that common ?

I’m not a snail expert, but my astreas do not have those sharp edges (crown like). But either way, that’s really cool.

The tank is a 150 gallon mixed reef that's comparatively new (6 months). I obtained the adults that were sold to me as spiny astrea or deep sea astrea. I have the ugly stage still going on with a diatom bloom so I chucked a handful in the refugium area. The other types of snails I have in the display are white ceriths, nassarius, bumblebees and banded trochus.
