Think this is a trochus snail but...

Found this little guy about 1-2 weeks ago - kinda looks like a trochus based on pics I've seen, but I am definitely no expert. It has two tiny antennae that feel around constantly and it moves fairly quickly for what I'm assuming is a snail.

Forgot to mention size - about 2x2 mm when I found him - now 4x4mm

What color is the foot base and skin around the foot? Shell looks like a trochus.

It's a trochid. But the first pic looks like a different species from the next two.

Thanks!

Thanks!

The foot base is very light tan to white, but I was viewing it through diatom on the glass, so it may actually be even lighter than it looked (more white). His antennae are definitely white, too. All pics are definitely the same animal. Sounds like the consensus is trochus - thanks for everyone's help!
