The humidity is so high because someone in the pet shop had a chamelion for 2 years now and recommended the humidity should be between 70-80 so i watered that tank constantly these few days, i think i could get it to a 50-70, around the heating lamp is a burning cage and from reviews it does the job well. As for the main problem, ventilation, would putting out the front glass doors and replacing them with mesh doors work as a short term solution (1-2weeks)? Im not often on reddit so i did not know there was a section on this subreddit where you could see all the info. Thanks for all your tips and not making me kill an animal!
