Hi Nancy,
I commend you for doing your research well in advance and being prepared – and yes, you will find mixed info. ChamNews has an article on Brookesia (the other small cham species) that may be helpful to you as the requirements are similar (see link at end).
I had a trio of R. brevicaudatus last year that I lost after 4 months. We do not know why. They were in "optimum" habitat, captive born, got them from a well respected breeder, had researched for quite awhile ahead of time - in other words I had done everything right and was devastated when they all died within a matter of days of each other
. There is still much unknown about them especially where supplementation is concerned (whihc may have been the cause). I tell you all this first just to let you know what my experience was. That said, I would get them again, I would also get them from he same breeder, however I do not recommend them for a first time cham keeper. I know they are adorable, and yes, some folks have been successful with them first time out (trinacliff, on this forum, had similar losses to mine but still has a couple).
One of the things that make them so appealing is also part of the problem - their size. If they have an illness it is very difficult, if not impossible, to diagnose and to treat. I do recommend you secure a knowledgeable herp vet before even thinking about getting them and one with some chameleon knowledge.
OK, you asked a simple question and I gave you a dissertation! LOL! I do not think you could maintain enough humidity in any sort of mesh enclosure. A tank is best with screen top and good ventilation (one side or slotted at top as well). They need more ground space than height, lots of highways and byways to travel back and forth, cool areas to retreat to, regular misting…
So if you are determined to get them I would suggest getting captive born, get from a reliable, knowledgeable breeder, DO NOT buy them from a pet store and if you get them at a show…well, again, know your source - and MOST importantly have a vet already lined up. I see you have some herps so this may not be an issue
