Bearded Dragons take responsibility and should not be given to someone who can't do what they're told.
These lizards are very playful but need a lot of attention and care. They usally grow to be 18''-24''; some can get up to be 30''.
I have had my Bearded Dragon for about 4 years; so far it hasn't been easy taking care of her. She is an inland Bearded Dragon, and is 16'' long. She eats lettuce and crickets.
