You say I need a small area, and then I don't need a small area. I think that is what you meant. Are you saying the spot lamp is good or bad? (BELOW) You never explained your setup. Lamp & bulb or just bulb? Do you put your lamp on your lid directly? Maybe she isn't too small then. Is your females like an inch small than your males though? How big are both your male and females?
*quote*With Cresteds, you don't want to heat the entire cage. They require alot of air ventalation. Just heat a ["small area"] to about 85 degrees. Spot light produce a lot of heat in a ["small area"] *unquote* (ISN'T THIS WHAT YOU SAID I WANT)
