You wont see the blue in the Boesemani's until they are mature(3.5-4 inch range) Mine dont look as blue in the front as the last pic shows it all happened in the camera somewhere. Mine arent mature yet either. The coloration will get better if you add some females though. What sized tank do you have? I run two females per male. I have a 29 gal planted with the following:
2 Glowfish Danios
6 Boesemani's(2 male, four female)
3 Bronze Irianian Rainbows(1 male 2 females)
3 Blue Platys(1 male 2 females)
plecostomus.

Decent bioload for the tank not overfull.
