Lyretail Swordtails

[Jambot]

Hey guys. I was wondering how to differentiate the male from the female when it comes to lyretail swordtails. I bought a male/female pair from my lfs, but they both look the same to me. I plan on getting two more females, but I want to be able to tell the genders apart before I buy them. It's easy to tell the gender of regular swordtails since the females don't have the "sword" tail. I tried my hand at google but couldn't find any pictures. Thanks!

Males have the gonopodium and females the anal fin. On lyretail swords the gonopodium is usually far to long to be of use for reproduction.
