Baby Snail ID

[EnterName]

I just received some Zoa frags today and found this little guy. First I was worried to have found a Sundial snail, but the pattern isn't quite right and the shape makes it look more like a nerite snail. I assume it's just a baby Checkered Nerite (Nerita tessellata), but before I put it into my tank I wanted to make sure.

It's roughly 5mm long (1/5 of an inch).

Did an image search and a Tiger Cowrie showed up. Looks pretty close anyway.......

It does have the pattern of a tiger cowrie, but the shape and autonomy of the snail is a little different……. Maybe it is one of those snails that are nocturnal and very small until a certain size. I cannot remember the name of them though……

I'm late, but Checkered Nerite or relative would be my guess too; also, for telling if you have a Sundial Snail or not:

Sundial snails prey on cnidarians like corals and anemones, but they do look fairly similar to Colloniid snails (and some others from the Trochoidea superfamily). That said, aside from their operculums which are a highly distinctive feature (the "horn"/"cone"/"rattlesnake rattle" shaped thing they close the entrance to their shells with - see the links below for examples), these are some other ways to differentiate them:

Also, for what it's worth, sundial snails (taxonomic family Architectonicidae) -even the more plain ones - are typically very, very ornate with their shell color, color pattern, shape, texture, etc. Many of them also basically have a flat, disk-like shell, and the ones that don't typically have shells that go basically straight up with their heads tucked in pretty far under their shells
