So I bought a bunch of rams from the store. While there i thought there was 3 F and 2 Males. But after looking them over I am not sure anymore, can anyone help me sex these monsters?

I believe the 3rd pic is a female, just cause the vent on her is massive and pointing down.

Bottom one is def a male, pointy and towards the back, plus the claudal? fin are extended along with the tail.
 
I can't see well enough to sex them, but I'm not so sure they are M. altispinosa. I'm seeing a caudal spot on them, which is just about never visible on live altispinosa. So I'm thinking they might be their close cousin M. sp. Zweifleck.

I guess it really doesn't matter to me if they're not true Bolivians. I think they were gorgeous in the store.

I would assume that sexing them is the same the Bolivian, correct?

Ill try to get some better shots, I had the camera zoom'd all the way in on those.
 
Yeah they are in great shape. Did they come from the store like that or was that from your care?
If you can get decent pics of the vents it will be easier to tell.

Store, I have only had them in the tank since Monday. They're just starting to warm up to their surroundings today.

Yeah so basically if it's a wide bump pointing down it's female and if it looks narrow and pointy and points toward the tail it's male.
That's a pretty good video, the one with the long ventral fins is a good looking male. Just looking at the interaction and the way the other fish follow 2 of the others you may have 3m/2f.

Yeah, that 1st one in the video is the one I was unsure of. So 2 female is what I was hoping for. Leaving me with 3 males, I'll let them stay together and if/when the two females pair up I may just pull the 5th wheel and move him to a different tank. If he doesn't get beat up to badly I may just let him stay. Its a 40g breeder son it should be enough room for all them. Especially when I transplant the plants from my grow tank into the 40g.

Thanks for your help Gillie!

Oh really? I thought that was apart of their species (blue,Bolivian,etc) monogamy? I'll have to read up on that!

Can they already be pairing and prepping to mate!? Its only been 5 days! The male and female have claimed one of the pots, and they are clearing the sand out of it. The female is also twitching her head and the male is around with both them in the pot!

Haha, I posted earlier that you might have a day before it happens, but apparently the app didn't feel like posting it.

But just a warning, if the eggs hatch and fry make it to free swimming, they will be about 3mm long.

Your lucky! I've had my Bolivians for a few months and they haven't even paired off yet!

Congrats and good luck!
