Need help sexing my Bolivian Rams!

[Ewiggins89]

I have three rams in my tank that I got as juveniles. Now that they have developed a little more I believe I have 2 males and a female, but I can't tell for certain. Any help is appreciated.

I believe the first two picture are males. I'm hoping that the last two pics (it's the same fish) are of a female. Thanks for your input in advance.

The first one looks male the others I can't tell really since I'm on my phone and they are pretty small on my screen. Look at the anal fin the males are more squared and pointed while females are more rounded. Also the breeding tube on females will be larger than males.

Only in the first pic is that one a male
The rest are females.
