I have heard that AFTs are sometimes very difficult to get switched over to mealworms, although I haven't had too much trouble with my small group. I have a pair of amels that I've had for a few years. The male switched over to mealworms very easily, but the female took longer. I haven't had an issue getting any of their hatchlings to eat mealworms. This spring I added a het patternless male and a whiteout female to my group. Both eat mealworms readily - especially the whiteout. However, they all seem to prefer crickets and since I have some Australian geckos that will only eat crickets, I feed the AFTs both crickets and mealworms. My female amel really needs crickets during the breeding season as she still isn't that crazy about mealworms. I'll bet roaches would work well as they are active like crickets.

The Urban Gecko and JMG have some of the newest morphs. AFTs are really getting interesting! GeckoForums.net has a few active AFT breeders and would be a good source of info for you.

Hope this is useful for you!
