Snail Expert Needed

I recently bought 4 nerite snails from my local fish store. There is 2 zebra nerites and 2 tiger nerites. The issue I'm having is with one of the zebra nerites. They are in a 55 gallon with my goldfish just for algae cleanup and mostly because they are cool and I like them.

So I got home and floated the bag and made sure the temperature was the same, and then I put them in the tank, blah, blah, blah. But the one zebra nerite climbed to the rI'm of the tank and I have not seen him in the water since then. I've had them for about a week now. There is no cover for the tank, only a light. Every morning I find him somewhere (first it was just the outside of the tank, then it was the stand, then a hanging plant with a leaf touching the rI'm of the tank, and this morning it was the wall behind the tank.) I always put him back on the rI'm of the tank, but he never goes in the water.

I've noticed that his design is somewhat different. Its not as bright as the other zebra, and it seems like a lot of smaller lines. Sorry, hard to describe.

Is it possible that this isn't even a nerite snail? I don't know really anything about land snails so I was hoping one of you could help me.

I'll put up some pictures. They aren't the best. I tried to capture the shell design, the growth pattern, and the snail itself or what I could get from holding him upside down and trying to get him to crawl out a little.

 

It looks like a nerite to me, but the zebra should have stripes. Hard to see those on this pic. @ can say for sure.

 

here are the first 5 that didn't load for some reason.

 

I'm not sure that's a nerite? What happens when you throw it back in the water?

I've only done that when I first got it. Crawled right back out. Even on the way home from the fish store I noticed that it had crawled up the side of the bag right out of the water.

 

Well, the one pic looks like the snail has a ramshorn curl to it but I know it isn't...I need to go back to remedial snail school.

haha.
yeah I tried to get a picture of that. Its kind of almost cracked off right at the middle.

 

Is it trying to lay eggs? Some snails leave the tank to lay egg sacs.

Do you have something with a cover? Try filling up with a few inches of water. Leave half empty. I'd be curious to see what happens.

Like just a little tank? To see if it does lay eggs?

 

After looking at this photo, could be a nerite.

Definitely looks like a Nerite to me but I can't tell you the exact variation. There's one kind that looks kind of like a "Southwestern" pattern so maybe one like that? There are literally tons of different patterns and varieties ( who knew?!?!?! )
And it definitely ACTS like a Nerite. Those things ALWAYS climb out of my water!!! They can stay like that for several days too!
I now have glass lids on my tank but my old tank, I had to use that Press and Seal stuff ( Saran wrap doesn't stick well )

Maybe someone can ID exactly what kind of Nerite it is for you

 

It is a leopard nerite.
Of all the different nerites I have, this one is strictly nocturnal and is constantly leaving the tank for adventures. You need a secure top and places for him to hide from the light.
