It is very difficult to sex Bolivian Ram when young, which is the size usually seen in stores. Have a read of our profile on this fish, it explains the gender differences, but again this is only reliable (somewhat) in larger fish.
And from my personal experience with these fish--and I have a pair herding their fry around my 115g tank as I write this--you should add them all at the same time. Same as with angels actually. Adding a ram later when one is already "at home" is asking for problems. If you can get a true pair, they will be fine together from the start. If you get two males they will establish their individual territories from the start (once settled) and should be OK. If you add a second male later when there is a male in the tank, the second male may well get killed. A cichlid stakes out its territory and defends it agains other cichlids of that species, and when a "new kid on the block" appears, it is often made very aware that it is not welcome because the original considers the tank his domain.
As noted in the profile, this species does very sell in isolation (one fish).
