I feed mine the same veggies my beardie eats as well as left over fruit like apple cores, loose grapes, mango rind, stuff like that. Also feed em Repashy bug burger(dry) which they love and cricket chow, chicken mash and fish flakes. I usually leave the veggies in there for 2 days if it survives that long but fruit is removed after 1 day so I don't get fruit flies. That's also assuming the fruit lasts that long.
