Ok so the mvb will be ok for now by its self but you are gonna haft to invest in one soon-- uvb and basking temps are crucial.to the dragons health - so get a power sun 100 watt or a mega ray 100 watt- distance should be 12" above basking decor w/ out screen if it's on the screen 8-10 inches w/ your basking decor directly under it--- make sure your getting a temp w/ your probe / cross reference w/ your IR gun-- temps 105-110I cant afford a UVB
But ill definitely get a different MVB. And his tank is one of those wooded tortoise cages. Be he seems to really like it. Its about 40G. A little bigger I think.
