Are these Irian Red Rainbows and what sex?

[Mosko]

I just bought these Rainbows from my local lfs. They were marked as Red Irian Rainbows. Can someone please tell if these are in fact Red Irian Rainbows? And also, the guy that helped me wasn't so sure but he believes 1 is male and the other is female. I'm just not sure how to sex them?

Looks like a pair, in the first photo male is above, female is below.

Which photo are you talking about? in 1 photo they're side by side, in the other photo they're above and below?

In the first photo the male is slightly higher than the female, though they are close to end to end.

Also how can I get the best coloration out of them?

What about the 2nd photo? also, how can you tell a difference?
