I have 2 bearded dragons and when i talked to the breeder of mine he said that meal worms were not a good diet item, that they were good for a snack once in a while. I give mine crickets like 3 times a week, and greens and fruits the other days. Mine are to small for the roaches, and i do have the phobia of the roaches... i know that they cant survive or breed in the weather condit that i live in, but still freak the crap out of me.
