Hello, I’ve kept two c versicolors previously in these exoterra enclosures except they had steel mesh tops which was a ton of ventilation. I replaced the tops with plastic to help retain heat in these colder months and to avoid their feet getting stuck in the mesh (it happened at once with my previous t). There are 8 vents on the bottom front portion and the drilled holes on top. The sides are glass and cannot be drilled. Do you think this ventilation will be adequate? Thank you !
