hello guys. i always loved lizards but never had one beacuse i never had time for it. But now i do have time so i desided to buy a Pantherchameleon. I searched on the internet about some things i didnt know about them but i couldnt find a few things: 1. can (Panther) chameleons always change color? 2. is a male more aggresive then a female? 3. what is a good price for a PantherChameleon?
