wow congrats... yes they do look like ulu's especialy when you can see the spots. Keep an eye on their thorats, if one has any sort of bluish tinge it is a male. Your heavier set one is definitely a girl. She will share food but they are very happy to eat 3 crickets each daily.

Congrats! and good luck if you plan to breed them I am planning to try breed mine if possible as you can see by the photo...they are very cute with their big dinnerplate eyes
