I come from nearby malaysia so I would just like to give you some precautions. Firstly, take nothing from the shopkeepers in malaysia, they know absolutely nothing. Stick to research from forums like these and mass breeders online.
Given the information you have stated, I would say that it would be more wise to pick a sub-adult to adult bearded dragon. Lastly, being in malaysia makes you unable to pick out the standard vegetables chosen by american bearded dragon keepers. I suggest stuff like Bok Choy, Kai Lan, the occasional cabbage and not lettuce. Fruits wise, you've got a choice but stick to the safe stuff like mango and papaya, no lychees, longans or anything like that. Cactus pad will be a good calcium "adder" if you can find it in the supermarkets.
