First a crested gecko, then a frog and now a veiled chamelion?! Dude make up your mind! Also buying a veiled chamelion its not like buying a gold fish. Even if these are some of the more hardy chams around, chams as a group are some of the most delicate lizards avaible and with the exception of grownd leaf chamelions(say Brokesia and Rhampholeon hopping I spelled correctely
) a terrible choise for glass terrariums. With chams there are many more stuff to worry about than most herps like possible strange nigth time temperature dropps, the need for fogg machines, if you want only one it needs to be a male and they even require as staple the most expensive insect foods like locusts and roaches. This is really something to think about. Most of the big chams love to be housed outside if temps allow it
