This has SO much information and I think you will find everything you can.
For my water dragon, the best thing to do is provide a varied diet, they get bored easily. One day meal worms, the next day dubia, next day butter worms, next day silk worms, etc.
I think that is the best thing you can do is provide a variety. If this is a new dragon to you, I'd suggest getting a fecal done by your veterinarian to make sure you lil guy does not have any parasites and have a thorough check for things like mouth rot etc.
Thanks hope the site helps. I spent HOURS on there!
