I have 200 Gallon tank that I am turning into a vivarium, its specs are 82x32x26. I plan on putting carpet chams, I know glass is usually not good for chams but because, its such a large enclosure I am hoping glass want be a problem. I wll also be beputting a few giant day geckos and mantellas at the bottom. Any suggestions would be appreciated. I am thinking of putting 1 male and 2 females( carpet chams). Is that good ratio?
