Tell me how to mix these..

[dstoneburg]

Im looking at doing adding an orange and white and a black and white and I would like them to pair. How/in what order would you say to add them, and any special advise for doing this?

I assume your talking about occelaris, you could buy a pair with noticable size diffrence, the larger one will become a female. i did this anouther way though. i bought a pair of black occelaris, the smaller one got stuck in a powerhead and diead then i go a orange one, and after the female made sure whos boss, they paired up.
