I woudn't worry about removing that glass...it should hold the temp and humidity OK as long as you spray minimum of twice daily and have a good basking light. Is this for a panther/yemen? All front mesh would be my advice (and I don't have double glazing in my house)
The plants look lovely...and it looks a good size for an adult panther
Hiya, I'm in the U.K and i use a mesh viv with no problems. I can keep agood range of heat for my fella and apart from bloody crickets walking all around it then its fine
I dont think that the glass fronts on your good looking viv are goin to be practical for a cham as they just will not get the air he needs.
