i would look at some pvc cages such as the animal plastics t3 or t8 they are both on sale at this time and they are supposed to hold heat and humidity alot better than glass tanks. i am making the jump from some 20 long aquariums to the animal plastics t3 i wanted to go with the t8 as it is bigger and 25.00 cheaper and ships in 10 days but i had to go for the t3 as the t8 would not fit in the space i have.
