CHAMELEON VIVARIUM SET-UP
Unless you are super-rich you do not want to keep buying more vivariums as your chameleon grows.
Bearing in mind that Yemen's grow to about 18" long fairly quickly it is far more economical to buy a large vivarium at the start.
Chameleons cannot tolerate high temperatures, low humidity or stale air.
You need a aluminium or nylon mesh vivarium such as a Zoo Med XL ReptiBreeze

or better still theZoo Med IguanArium

or the Exo Terra 100 gallon Flexarium

Mount a 100 watt mercury vapour UV & Heat lamp on the top of the metal mesh to provide heat and essential ultra-violet light.
With nylon mesh suspend the lamp a couple of inches away from the roof to prevent the heat of the lamp melting the mesh.
Substrate should be a thin layer of FINE Orchid [Reptile] Bark

You also need a good quality spray bottle as chameleons do not drink from standing water, only from spray or water droplets on leaves.
Many local tree branches produce toxic resins, only use commercially prepared branches for your lizard or use FRUIT Tree branches as none are known to contain toxins.
You need good quality dusting supplements such as,
Rep-Cal Herptivite Multivitamin with Beta Carotene

Rep-Cal Calcium without D3

Dust all live food with the calcium 5-days-a-week and the vitamin powder the other two days.
