I notice this Also.
Really been looking into maybe getting one, but can't find much info either. They are really rare in the UK and big money when avalible. Would love to learn more about them before commiting to looking after one. Amazing creatures
I mix it all up. I give fully gutloaded crickets, large locust, adult winged locust, dubia roaches' giant banana roaches, butterworms and silkworms, no mealworm or wax worms. I found the most important bit is the gutloading. :)
