Hi Vicky !
The only difference I know is that the ladies will lay eggs, and the boys won't.
Okay, I know that sounded rather, lame, but truly, that is the only difference. Me and my sons didn't want to deal with unfertilized eggs, so we have all male dragons.
Keep reading and asking questions, that is how you end up with happy, healthy dragons !
Here on this forum are lists for great foods :

Even more dealing with photo love of dragons, so the lists are endless.
Start with the basic care list, and work down from there .
Hope this all helps you out, and can't wait to see your new dragon(s)!
Janie.
