When I set up my very first enclosure for an emperor scorpion, feeding was the part that made me both excited and a little anxious. These scorpions are obligate carnivores, so their diet in captivity should revolve around live insects like crickets, roaches (dubia roaches are a top choice), mealworms, and waxworms. For juveniles I used pinhead crickets and small flightless fruit flies, then graduated them to medium crickets and large dubias as they grew. I always try to match prey size to the scorpion's body—no prey wider than the space between its eyes—because too-big meals can stress or injure them.
A few practical habits I picked up: gutload feeder insects with calcium-rich foods, remove uneaten prey after 24 hours, and offer a shallow water dish that’s refreshed daily. Adults can be fed once or twice a week; youngsters need feeding every 3–4 days. I rarely give pinkie mice—only for very large adults and sparingly—because insects provide better nutrition and lower risk.
One little thing I love? Watching them hunt at night under red light. It’s oddly satisfying. Just be mindful of molting: they'll refuse food before and after a molt, so give them space and humidity instead of trying to tempt them with treats.
