He's so cute!! =)
Please do ignore the bickering above~ <3
a few rules of thumb that most people seem to agree on are try not to feed anything larger than the space between your dragon's eyes.
Let younger dragons (like yours!) eat as much or as many bugs as they want per feeding. Sometimes mine eats 8 for breakfast. Sometimes he eats 12.
I offer both bugs and veggies. It's a good way to add vitamins to the diet, but also it helps you determine what your beardie likes or doesn't like. (...Skywalker hates blueberries, for example. Not a fan of Kale so far, either) So now, as he grows older, and adult dragons eat more veggies and fruit than bugs...I'll already know what he likes, and he will already be used to having it offered to him.
For now, I offer veggies in small amounts like treats more than meals. But he likes them!
