I'm guessing it probably needs a very specific diet and climate to survive. If this is like other chameleons, they are prone to all sorts of health issues and in general very hard to keep alive.
Nonsense, a shrewd capitalist can easily sell these in kits with everything you need to keep them alive. They are so small, and if they die well they are tiny you can probably just get a new one and most people will probably keep like 4 or 5 of them at a time anyway, probably breeding their own replacements. These are fantastic can’t wait to have a terrarium filled with them.
