-hiya, hope i can answer some of your questions......
how long do bearded dragons live?
-i think the longest a dragon lived in captivity was somewhere between 11 and 15 years but on average they can live 7-10 years with proper care a lot less with improper diet and husbandry.
how large do they get? compared
to other pet's,
-some dragons can get up to 24 inches long and maybe 700 grams, average is about 17-18 inches 350-450 grams (these are just guesses based on my dragons) i would think, not all of them get really big, some stay on the smaller side and then some of them really get large
is taking care of them properly expensive?
-taking care of them is moderatly expensive, one dragon wont put you in the poor house, but expect weekly expenses on greens and veggies as well as buying live feeders such as crickets or superworms or silkworms etc. There is also the extra cost of heating and UVB lighting, the initial set up will cost maybe 150 dollars depending if you build your own enclosure, buy one etc
and what about temperment?
-temperment does always depend on the individual animal but in general, dragons have excellent temperments, are easy to handle and are wonderful animals to watch, they have great behaviours.
also do you recomend a good book on the subject?
-a good book........im sure someone will be able to give you a good book, i cant remember the name, there are great websites out there as well that have great information, try this site, http://www.beautifuldragons.com/ she has a lot of info there, also you can search for care sheets on your search engine and read till your heart is content, there are a lot of care sheets out there, read and compare information and then ask all the questions you can think of! =E
Thanks a billion,
