Well yesterday I bought a new 29g aquarium for my Central American Boa and when i was getting ready to feed him I found him dead

. I kinda thought something was wrong, since he fed regularly for the month I had him/her. But he seemed to just get skinnier, well I purchased a surname female local breeder from a very reliable retile store in my area. More reliable than where I got my CAB (petco

).
But my first question is I'm using a 75watt Zoo Med infrared lamp, is this enough or too much heat for her?
The encloser has a granite water dish large enough for soaking, Humidifier tube, frehs air tube, corner half log hide, 2 plastic vines over near water dish for hiding, silk plant with rock base near half log, and plastic "twig and rock for climbing, also using a ESU T8 uv florecent bulb during the day.
