Ten gallon is way too small for even a young hatchling. You need at least a 20 gallon long to start out with to allow for proper temperature gradients.

No loose substrate of any kind. Ever. Only paper towels or tile for hatchlings and young dragons.

Do not cheap out the equipment, go with high end UV lighting. I recommend Mercury Vapor Bulbs because they cover heat/lighting/UV all in one bulb.

Hatchlings eat 75% protein in the form of small crickets. No mealworms or any other hard shelled worm until the dragon is 6 months old or at least 10" Impaction is a major issue with young dragons.

Baby dragons eat first and ask questions later. They WILL ingest substrate as they dive for crickets and they WILL get backed up if you feed them mealies.

Adults eat veggies and salads more so than crickets and roaches. The switch from 75% protein to 75% veggies begins at around 6-8 months of age.
