What kind of Nerite is this?

I got these two at Petsmart today. I don't know what the big one is. All the zebras I've seen online have been black and white, and it doesn't look like a tiger either. I know that the little horned one on top is a Bumblebee. I love them--so cute! My pics won't download!

Is it the shape of a tuque? If so its a jokey nerite.
