I'm really surprised they're all healthy!! I came up with the idea of setting up several vitimin water caps (bigger than soda caps) filled with unused fish marbles. They get the idea and they don't get wet. If anyone wants to see my idea tell me and I'll put up a pic!
Today I put 10 crickets in the cage.They turned into little murderers!! They ripped them apart and ate them ALL! I'm happy I found a healthy treat/activity for them LOL.
I'm glad they're all doing so well for you. I was worried about them because of the extra long trip and the heatpack deciding to crap out. Have you tried handling the male yet? He doesn't exactly like being held, but he was always pretty calm for me.
