sometimes they will eat each other, though it is uncommon with emperors. your best bet is to not get stung, it shouldn't be that bad, but you never know how you will react until you get stung.
Ok guys I feel really confident now that I will be ok. As soon as I m done with school 2morow I will pick a pair, just hope that everything will be fine!
Hey, just make sure you keep their humidity at around 80%. Feed them crickets and mist their cages and the substrate, which should be something like eco-earth. Provide some hiding places for them as well because they are nocturnal. Don't expect them to be very active during the day.
