Difficulty sexing Bolivian Rams

[jessa10]

Hello, I have two Bolivian Rams that live peacefully in my tropical community tank. I have absolutely no issues with them at all, in fact they are so wonderful, I am considering getting a couple more and I will need to know if my current Rams are M or F. I took two pictures of each Bolivian and I can take more if necessary. Thanks.
