you should not feed them dragon pellets, that does not stimulate them at all.
Ben if you are not willing to look after the beardie rather do not get it, most of us take pleasure with our animals, we like to look after them. If you just want it coz its cool then please leave the poor animal, im not trying to offend you its just that you seem to be wanting to take the easy route on this.
You need to feed the beardie protein (live prey ) is always the best, not frozen, canned etc..
You can feed them Ga Ga grubs, but they will go through alot of those as they are tiny, and also you will find that after a week or so the grubs turn to flys if you have not finished them.. i went through a tub of grubs in 4 days with my beardie over 200.
You need to feed your beardie a decent meal, at least 3 times a day, that is highly important if its a baby, as babies grow very fast. I feed mine in the morning and evening.
