westAfricanspurs in doors use Mercury vapor bulbs on them its heat and uvb in one as they grow you will just have to add more bulbs to the indoor setup to properly cover his whole body when basking
if he can see out like a glass fish tank you may want to cover the bottom 3-4 in with a cheap window film or aquarium backer just around the bottom like a little fence this will stop hes urges to try to walk through the glass they always think the grass or glass is greener on the other side.
