I live in the North of the UK so its pretty cold here most of the time, a lot of people here resort to glass vivs to get the correct temperatures from what I've seen, but ive read theyre bad for chams so I got a screen cage with a stronger bulb, ive never seen him show signs he was uncomfortable with the heat, (no keeping his mouth open etc) his temps are usually around 30 c which is about 85f, reptivite is without d3 and miner-all is indoor i bought the supplements as part of a pack recommended for chameleons on Internet reptile
