I would guess male for the first one because of the light colored dorsal fin, females usually have a dark spot in the dorsal fin.

Because they are so young it is a tad early to jump to any defined conclusions.
I do see a dark border on the dorsal of your 2d shot, that, if that dark colors spreads over the entire fin, "might indicate female.
a female normally looks like this when old enough, and in the presence of a male.

Without a male in the tank they are less obvious, like the same female below

Here isa pair together

For me the females didn't start coloring up until about 4"

Thanks, that helps! At what size can we say with certainty whether it's a male or female
