Not a bad idea. The little one is A LOT smaller than the big one. Talking almost 2 inches to about 3/4 of an inch. Is that normal for them?

Yeah that is a way used by stores to prevent them from fighting. So when they pair fish, they take one big and one small specimen. Mostly bigger will be the male and smaller will be the female (or vice versa in certain fish).
If you mix fish that are about the same size, there will almost always be fighting, even if they are a male and a female. Size difference predetermines the hierarchy and who is dominant, so there is very little to no fighting for determining that.
