You might want to do more research on these fish first. One pair alone is probably not going to give you what you want. They need some of their own species around to swim with and males show their best colours and behaviours with at least one other male to show off to. Once in breeding condition, you take the best looking male and fullest female and put them together in a fair size tank to spawn. Fry are not the easiest to raise either.

Females are smaller and do not have the colour that males develop. Mature males have the beautiful colour these fish are known for and are larger, deeper through the body. If the fish in the pic is full grown, it's likely female.

One good source of info is here. Melanotaenia boesemani (Boeseman's rainbowfish) — Seriously Fish

No, sorry, I can't. I have a friend who keeps these and breeds them successfully, but I don't have any. I know the full grown males have this gorgeous coloiur, and he has a number of them, and has been quite successful. Very picky, careful type of guy, takes a lot of time and effort with his tanks, I think he has about twenty of them running now.

If you got it from a breeder, chances are he got the sex right.. but immature fish are often harder to sex in general. Best of luck.

Most LFS only order males in because the average person will buy all the males and leave the less colorful females behind.
