He's my pride and joy! Or he will be, once he stops being so derpy. Overall, I spent £200-ish on his vivarium (tank), substrate, basking bulb, UV bulb, fittings, in-tank "decorations", etc. He only set me back £29. And no, he's not difficult to look after at all!
Bearded dragons are the easiest form of reptile to care for.
They're omnivorous so they eat crickets, mealworms, lettuce, tomato, etc. - and once every so often, he gets treated sweeter fruits like melon or apple. The most important things are to make sure that their temperatures are right (70F - 90F on the cool side, 90F - 110F on the basking side), that they're healthy, their food is calcium-dusted, and that you handle them a lot.
