1. I think what she meant by that pygmys are ground dwellers that mostly live on small plants and bushes.
2 you would have seen she said tree and your plant is not a "bush" its a bonzai tree, the thing is they go for length rather than height that's why she said 20height if you did research youd know that length is more recommended for them as opposed to height like veiled chams are.
3. That is why you didnt understand the last part ill give you a link to what she meant

and about the thing of not moving it was just a misunderstanding of this statement "he doesn't act at all like there is ant desire to leave" . I'm glad your tree is working for your cham but dont be to quick to question the members that are just trying to help you some of them have kept pets for a long time I myself learned that once. were just trying to help

welcome to the forums and enjoy your stay. Hope you and you enjoy your new buddy and maybe get more chams in the future.
Thanks for the advice...I skimmed it long enough to find this:
"I prefer "tall" aquariums (or something around 16"/17" high) especially for Rhampholeon brevicaudatus. My group tends to spend their time in the foliage/branches as opposed to being on the ground, so taller plants are preferred and therefore a taller enclosure."
I am a member of lots of forums, and I have kept herps for lots of years, since like 1974. I know chams are extremely specialized animals, which is why I started with brevs rather than acuminatus, viridis, or temporalis. I wanted to get my feet wet first.
I am not trying to be rude, and I do not want to get off on the wrong foot on this forum. I am just calling it like I see it. I will need help, and I know this is the place to get it. These forums are amazing sources of hands-on knowledge.
They are also places where kids who have kept one white's tree frog, a ball python, and a calyptratus for six months are suddenly ready to give advice to people who have forgotten more about animals than they themselves will ever know. I wasn't "questioning" her advice...I was informing her that her advice was wrong...there is a difference.
It's kind of like forming an argument, then using a supporting document that doesn't necessarily support your argument...like you just did. My ficus is three times the size of the scheff in that tank. Last night with a red light I couldn't even find the little dude, and gave up.
The bottom line is this: If we don't correct bad advice, or ill-informed comments, young herpers can read it and might know no different. This helps no one...not the least of which are the animals. There is a ton of bad herp info out there, and I have no desire to be a part of its disimination. I am here to respectfully ask for help and advice from chameleon experts. So by responding in the manner I have, hopefully will keep the "self-described" experts from trying to help me, and get more help from the seasoned vets.
Like I said earlier in this thread...there are very few Steve Irwins in this world...but there are a buttload of Dr. Brady Bahrs.
I want advice from The Crocodile Hunter, not the guy who wades into a cave in the Phillipines through 4ft deep liquified guano, finds a 12ft retic, and grabs it...only to get bitten on the thigh and proceed to scream like a 13 year old girl watching
The Ring, like Bahr did...have you seen that? HIGHlarious and sad at the same time.
I hope you all have a Merry Christmas.
