Hello, I have a 3 month old dragon and I need help with what he needs. Right now I have ReptiCalcium without D3, Organic Multivitamin Powder with D3, and Probiotic Powder. Please let me know how much I should be giving him, which of each and if I need something else. (He also has a Reptisun 10.0 UVB bulb on 12 hours a day)
