Since you are having problems maintaining humidity in a tank with a heat lamp, which is not unusual, I would suggest switching over to a tub with an under-tank heater that is regulated by a thermostat, or to a proper PVC reptile enclosure. Fish tanks are great for fish or species that don't need to have high humidity, not so much for snakes that need to stay warm and humid.
