Planning on picking up a male GTP from an upcoming reptile show. I was wondering what the minimum cage requirements were for an adult male. I've heard of people keeping adults in 20 gallon tanks and others using 3'x2'x2' enclosures. I have a 30"×12"x17" glass cage that has a hinged door in the front. It also has a glass lid instead of a screen top. I know glass isn't the best option but I'd really like to see this get used. I've seen a lot of people use the 18"x18"x18" cubes but I feel like with my dimensions the snake will have more length to choose a preferred temperature. Anyways, all info is appreciated. Thank you.
