EBR and GBR sex? Still confused...

[janky]

So I've been doing research for a couple of hours and I'm still pretty lost on how to sex GBR's and even more lost on the EBR's.

The lfs said I got 2 male and 2 female. I don't think I agree - judging by the pink bellies, extended dorsal fins (2nd or 3rd ray) and blue shimmer through the black spots.

Here's the EBR - I think this one is female, due to the dorsal rays being the same uniform size throughout. Thoughts?

GBR #1
Here's the GBR I'm having the most trouble with. Not a very colorful fellow; no black spot to check for shimmer. Belly doesn't look pink..
(It's shy, so very hard to get a good pic... I will try again later if this one isn't good enough)

GBR #2
These guys I'm almost positive are female; pinkish bellies, shimmer through the black dot - however they have elongated 2nd dorsal rays, which is really throwing me off...

Any thoughts?

Does the sex really matter? Sexing your fish is only important in a breeding setup. If kept together, these 2 color strains of the same species will not selectively pick a mate of the same color. If it is only a community tank, then enjoy the fish as they are.
