How would you divide this colony???

I currently have 6 males and 5 females in my grow out tank. I'd like to keep all the females as breeders. Any advice on how to divide them up? 1.2 & 1.3; 1.5 or 2.5; or even 5 pairs of 1.1???

feed off 3. males and make 2 starter colonies. 1.2 and 1.3 that's what I would do. I use the lab bins to breed mine and that's all the more adults I like to keep in those.
