Thank-you for the information. The 30 gallon is fine and eventually you will need a 40 Gallon breeder tank. The climbing vines are not really needed, as Dragons are terrestrial and need the floor space rather than vines to climb. I am very glad you replaced the UVB bulb, they do need to be replaced every 6 months. The big issue is inorder for the UVB to do its job, the Dragon needs a plain calcium supplement 5 days a week dusted on food and 2 days a week a Vitamin is needed. He is very young maybe 2-3 months old. 6 inches is very small to even sell a Dragon. Most reliable breeders do not sell them unless 8 inches.
Your Temps are a bit low. The basking ares should be 105*-110*F, the warm side 90's and the cool side 80's. I suggest you recheck them with a digital probe thermometer or a temp gun for accuracy.
No the Veggies right now should be 20% of the diet and the prey should be 80%. For veggies you can try collard greens, mustard greens, escarole, curly endives, butternut squash and you can take a fruit baby food and use it like a salad dressing to get the Dragon to eat. For prey you can use crickets, silk worms, dubia roaches, and phoenix worms. Sometimes the variety helps.
He is way too young to brumate, and we do not see that until a year or older in Dragons. If this behavior continues, then I suggest a Herp Vet visit for a Fecal and a Vitamin shot. I will give you a Link for Herp Vets in Virginia: http://www.anapsid.org/vets/virginia.html
