Hi Adeline....it looks pretty good ! You might want to add the big 3 greens to the list...turnip, mustard and collard. It may be best to feed the dubia [ or any live bugs ] earlier in the day so he has plenty of time to digest.
Be ready for a possible food strike for the first week or 2....some dragons can be stressed or just fussy when going to a new home. See how it goes, and have fun with your new pet.
