Well, look at those long pointed dorsal & anal fins & the 3 spots in the tail, that says male to me in the last pic especially. The belly doesn't look pink except a bit in the last pic. In some pics the belly looks pretty rounded, some much slimmer & not pink. Could it just be fat after big meals?
The newer "male" doesn't have any tail spots, p.pulcher females usually have 1 at most, sometimes just some color, not really a spot. I really think your newest fish is a p. taeniatus, it doesn't have "nose stripes" like pulcher...or the dorsal spot or blotch like pulcher females...waffling, lol. There's also something about the head shape that seems different & the more muted coloring...
Did you look at lots different regional taeniatus? I did not. There also may be regional varieties of pulcher nowadays or even hybrids between the 2, sorry I don't know...
Are they fighting? How about sizes? Females are noticeably smaller, think short & stout, 2 inches vs 3 in adults.
You might try posting on a dwarf cichlid or even a pelvicachromis board if there is 1, there are likely more ways to tell or at least offer a better guess. If you do I'd like to hear what you find out.
