Of course the upside is that they're personable & interactive. The one I rescued really loved to be cuddled- he'd snuggle on my shoulder & go to sleep. He could also be pretty silly when he was awake- like attacking his image in a mirror (thinking it was a rival male dragon he had to fight).
Make sure you're providing the right lighting to keep his bones strong too- real sunshine works best, but it's not practical for pets, except occasionally & with supervision. The artificial lights need replaced about every 6 months to be effective as I recall (unless they've been improved?)- as their output diminishes, even though they still illuminate- so be forewarned on that to avoid MBD.
