Tiger Zebra?

So I decided to add a couple Nerites to each tank. I picked up 4 pretty little guys this evening. While picking them out I thought I was getting 4 Tigers but once she put them in the bag one looked like a Zebra. When I flipped it over I could see a very distinct line in the shell where it turned from zebra to tiger markings! Is this common? Could it change back to zebra at some point in the future? Either way he's cool looking.

I'll add a pic as soon as I lay my baby down.

 

It's fully possible for the markings to change as they grow and end up in different water conditions. I think someone on here had one where the stripes started going opposite directions once it was introduced to the new tank.

 

That's cool. I haven't gotten a pic of him yet because he is busy cleaning the inside of the tikI hut! Lol

 

Finally got a pic of the Ziger Tebra Nerite snail! Lol

Yeah I like it too! Didn't even realize it was half zebra until she put them in the bag.
