yes I use the uvb light during the day and a heating lamp during the night. the uvb light is "exo terra sun glo" uvb lamp, i have this red uvb lamp (cant remember the brand, sry) but read it was not good so I got this one. however, at night when I put on the heating lamp the temp goes up to 100 and the humidity goes down to 45% (these are the max temp and humidity in the cage at night).

Ok thats what I was talking about!
The SunGlo is not a UVB generating bulb. It is only a fancy, overpriced version of the same bulbs that you have in the lights in your house! It is doing nothing for your ig. What you need is a UVB generating bulb. I would recommend the Mercury vapors from Welcome To ReptileUV - Mega-Ray® UVB lamps for reptile lighting worldwide. You can also use 2 4ft flourescent tubes. The Zoomed 5.0 are the old stand by.
If the temps in the room where you are keeping the ig do not go below 70-75 degrees at night no extra heat is needed.

Also, regarding the fruit you're feeding... go easy on the banana and fig. Bananas are an "occasional" fruit as are figs, plus the seeds in figs can cause problems in very small iguanas (like yours). Have you checked out our iguana diet page? If not you really should do that. I've linked to it here: Iguana Diet.
