nannostomus?

[JD.]

I have an aquarium of 180L with a trio of apistogrammas cacatuoides couple pulcher and soon will have its own aquarium and 180L eastern Amazonian biotope will try to reproduce the issues is that they want to get Nannostomus marginatus and mannostomus unifaciata and if I do not put the Nannostomus trifaciatus pondre marginatus, but I would put the two species whatever, Could get 20 fish of each species? the aquarium would be only for cacatuoides and Nannostomus
