What kind of snail is this?

Went to the aquarium store today and bought a couple nerite snails that had apparently just shipped in, on my request.

But these guys are clearly not nerites. I wanted nerites because they can survive in freshwater tanks, like the one I have, but the two I got seem to be saltwater.

What are these, and will they survive in my freshwater tank if I acclimate them from the saltwater bag they're currently in?

Someone suggested that they were ceriths, which they do seem to resemble.

Recognize them?

Yep. They're all ceriths (Cerithium sp.) to me.

Be very careful when buying your snails. I suggest you take pics first before you buy if you are unsure. Nerites vary in shape, size and colors. Many are confusing enough with several other species. The ones often sold are Neritina natalensis, Neritina reclivata, Neritina turrita, Clithon corona and Vittina waigiensis.

the shells do look like cerinths.. but i've never seen any that color before.. but that of course doesn't rule them out, just my experience
