Well since you're going to need supplements and vitamins, people find that Reptivite, Rep-cal, and Repashy are good brands. Reptivite w/ D3 contains supplements and vitamins, everything you would need. Rep-Cal along with Herptivite work well together, just make sure you're only using the multivitamin once a week. Seperate the feedings by dusting regularly with the Rep-Cal and using the Herptivite once a week.
Some people like Herptivite more than Reptivite because it contains beta-carotene, which much easier converts into Vitamin A for amphibians rather than just straight up Vitamin A found in Reptivite. Haven't ever used the Repashy line, but people recommend it if it is found in a local reptile shop around you.
