Strange Snails At My Lfs?

So, I went to aquarama today, a locally owned tropical fish store in my town, and they had some snails I had never heard of before.

In one tank, there were about 7 snails marked as "colored snails". They looked like regular mystery snails, and two of them were slightly bigger than I've ever seen a mystery. I asked what exactly they were, and she said "long antennae snails". Tried to research, didn't find anything. Does anyone have any info on them?

In another tank, they had what seemed to be small mystery snails, but the sign said "Asst. Snails" there were no assassins or even nerites in the tank, so what could they be?

And finally, they had 7 straight up apple snails. I know what these are, they were HUGE and I want one BAD. could I keep one in my 10 gallon snail tank? I'm pretty sure the answer is no, they are way too big, but I'm so hoping someone with experience says that a 10 gallon is fine for one giant apple snail.

 

A 10 g tank with just one apple snail should be fine. I have my diffusa in a 10g, but it's only with cherry shrimp and a betta. Apple snails come in many breeds and are often sold as mystery snails. My diffusa is only golf ball sized and fully grown, but other apple snails get the size of actual apples. They come in many colours.

 

but the sign said "Asst. Snails"

My guess is this is “assorted snails”.

 

Pics by any chance?

Sadly, no. I left my phone in the car. I'm going back to get a "long antennae snail" next week and will take some then, though.
