I feel a pelleted diet is great for beardies if they take it...most people I know use reptical and soak the pellets in warm water to moisten it. If you read the label it has a great balance of nutrients. It does not take the place of fresh greens and fruit, but it will be a wonderful addition to the diet.
Gimley loves Mesc greens and crickets. To be honest she loves everything

She has some appetite! I have to say, so far her favorite is tomato horn worms....she is never too full for that.
What color is your new beardy? Congrats! They are wonderful lizards!
