I'm attaching a link for the resources page here on the site in regards to care. As for "taming," there's a method to the madness, but it also depends on what species of cham your looking at and the individual cham you get. You can do a search for threads on that subject. Good reading.

As for recommended species, it depends on what you want out of your pet. Each have their different merits and pitfalls. Do your research on each you may find interesting and hit up folks here that have a certain species you're interested in. I could talk your ear off about Lucky my turquoise veiled. Don't hesitate to ask questions, do your research and read, read and read all you can and then, once you've made your mind up, read some more. Welcome to the madness that is chameleon keeping.
