when what you thought was a male is actually a female

[versicolor]

Sometimes males will lock with males for dominance ..

Really?? I never knew this. I know when I popped them both, the one male was definately 100% male. Had two good sized hemipenes pop out and sperm plugs as well. With the other "male" I could get absolutely no penes to pop. I got some urine, but no signs whatsoever that it is a male.
