Bearded dragons have a cheaper startup? Why is it so much cheaper for them and what makes them so much easier?
Also, do you know much about Chinese Water Dragons in comparison to Chameleons or Bearded Dragons?
I have both a chameleon and a bearded dragon. I have had 2 Chams pass in the time I have had my beardie. The first one from a bad breeder(all of the Chams from that clutch died) and the other had an eye infection that went septic. Beardie a are easier because they are heartier. They are much easier to keep healthy. Chams need to have humidity just right and temps just right. Beardie a need the right temps too but it's not as difficult to get it right.
Chams need to be misted several times a day. It's vital for hydration and cleaning out their eyes. Beardies you soak once a week and they get their moisture from that and from their feeders and their veggies. You can get away with a hand sprayer for a Cham but let's be real, are you really going to be around 3-4 times a day every day to mist? It's not that easy. Investing in a misting system was the smartest thing I did and it took me way too long to realize it. Mine cost $125 for a mist King.
Chams enclosures need to have a lot more stuff. Plenty of vines and branches of varying sizes. Plants for foliage to hide in. working out a good drainage system is a good idea too. With a beardie its basically a good high spot for basking and that's about it. You can spend a lot to make it awesome as I've seen some pretty amazing enclosures but making it pretty is not a necessity like it is for a cham(being pretty isn't the necessity but the amount of stuff is and it makes it pretty).
Basically, both need UVB lights, both need a basking spot, both need supliments and feeders. But yes, Chams will cost more. They have different needs and are totally different in handling. My beardie is my buddy and hangs out with me all the time. My Cham hates my guts. I've had ones that tolerate me but they don't hang out with you like beardies do.
I don't think a Cham is necessarily too hard for a first reptile as long as you do your homework, are ready to spend the money and are willing to keep learning and do what is necessary for the health of your Cham. But DO NOT listen to a pet store. A majority of the time they do not know what they are talking about. Every once and a while they will have someone that is knowledgeable but it's rare.
I would suggest going over to beardeddragon.org and studying up on them too.
Good luck!!
