I unfortunately don't have access to my camera right this moment but all I did was use my wood burner and made two large holes (about 2 inches diameter) in the canopy cover that lifts up and covered it with mesh (one on each corner and in the middle). It has worked well for me. The primary issue I am facing recently is that if the ambient temperature is too high in the room where the habitat is located (winter here) it accelerates the amount of humidity / heat in the habitat. I have designed a small fan unit but until I notice the humidity affect the mantellas I may leave the setup alone. The highest it has reached recently was 76% but that was for a short period of time.
