My male veiled once took a fall of about 4 feet (and I wanted to kill the woman who dropped him, a supposed "cham expert" who wasn't quick enough to hold him as he ran). He ended up with black on his side, where he had landed on some squishy toys... He seemed ok from it, bounced back nicely. Tho he did fall into a box of soft stuff... If the "bruise" lasts for more than a few hours, I'd take her to the vet asap... but a vet visit to check for any unseen injuries is also a good idea wether or not the bruise goes away. Try a shorter plant next time, or supply padding if you have to use the same tall plant... Hope she is well.
And a note about the new cham in your household... It's easy to get wrapped up in how cool chams (and herps in general) are, but know your limits in taking care of them. I recently had to find new homes for 3 of my herps b/c we had substantially more income when I got them... since having to switch jobs, I couldn't afford having 4 herps anymore. As much as it killed me to do it, I found 3 of them a new home with someone that I know will take good care of them. And down the line, I might get more, but that will have to wait until I have a better job & know I can pay for it all. You and your brother may have a harder time doing that (paying for all the unexpected expenses). Just know that really caring for your chams may, at some point, mean realizing that you can't care for them properly & need to find someone who can. Good Luck & read as much as you can on their care... =o)
