indisputably fantastic looking animals. whenever I see desert combos, I can't help but lament their reproductive issues.

I've also heard from multiple sources that deserts, especially females, are as ferocious as hatchlings as wild-caught animals. Justin Kobylka had a teaching video regarding the handling of aggressive babies, and I believe he uses his desert females as the feature. I'm sure it's unrelated to their infertility issues, but it does seem an odd trait to be inheritable across the board.
