ID Please!

Well I just happened to come across these little guys today at the local LFS however I have no clue what they are. I believe the one is probably an acei because it was in a tank full of them, but perhaps its a bit stressed out. I'm completely confused by the other ones. And it bothers me not knowing what they are. So do any of you have an idea as to what they are?

Yea after looking more into it the 3rd definitely looks like l. fuelleborni and I'm fairly certain that the white one is a hybrid between that and the red zebra because you can see the same orange-ish patterns showing up along the side of it. However I do think that the first one is possibly a rusty.
