What is he being offered aside from roaches and carrots? Alex can be pretty picky. She likes clovers, blueberries, dandelion greens and is coming around on kale. The fresh young greens are more palatable. She's not a fan of mustard or mint. Makes the "ew sour!" face. She loves squirmy wormies. Mealworms, waxworms, superworms are all greedily taken. That said the carapace isn't very digestible for them (think corn for us lol). Black soldier fly larvae trigger the same reaction of greed, but are much much much better. Also a lot cheaper but they come in bulk and pupate pretty fast. 500 for $10 or so vs $5 for 50-100 wax etc... I buy mine from Symton (sp?) based out of Texas. Great supplier. They can eat the pupae and adult flies if you can catch them lol Alex loves the adults. I think the buzzing wings are like fizzy candy or something lol The pupae may take a little getting used to. But once it moves a little they will get interested and realize it's yummy.
