Dedicated to Bolivian Rams

[Aqualady40]

Hi, I am a new parent of now 3 Bolivian Rams and I have researched how to sex them....I know one is big enough to judge and say it has male characteristics so it is a male....now the other 2, I think one is male and other is female.... not sure on them though.....check out pics of them in profile....feel free to express your thoughts on them...

edit:
I got the 3rd one today and want to know is it ok to have an uneven number because all was fine till meal time.....a little aggression...not too much....but how will I know who to return or is it ok to have 3 instead of pairs...

Tank:
Planted 55g
4 rosy barbs
2 bristlenose
4 julii cory
4 silvertip tetras
4 ghost shrimp
3 Bolivian Rams

I do not think so because they pair up then the third one is harrased get even pairs and tell us tank size also anything else in tank but I don't know cichlids well
So I am probaly wrong
